What is a hypertonic solution in chemistry?
In a hypertonic solution the total molar concentration of all dissolved solute particles is greater than that of another solution, or greater than the concentration in a cell. If concentrations of dissolved solutes are greater outside the cell, the concentration of water outside is correspondingly lower. Click to see full answer.
What is the concentration of NaCl in a hypertonic solution?
If a cell with a NaCl concentration of 0.9% is placed in a solution of water with a 10% concentration of NaCl, the solution is said to be hypertonic. Hyper means more, meaning that the solution that the cell is placed in contains more solute than the solution inside of the cell.
What is the concentration of the solution outside the cell?
The solution outside of the cell is 10% NaCl, which means that it is 90% water. The solution inside of the cell is 0.9% NaCl, which means it is 99.1% water. Remember, solution flows from a higher concentration of water to a lower concentration of water.
How does water move out of a hypertonic solution?
The process by which water moves out a cell in a hypertonic solution is called plasmolysis. Cells that lose too much water can be damaged, and organisms immersed in strongly hypertonic solutions can become dehydrated.

Is the solute concentration higher or lower in a hypertonic cell?
A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.

What is the solute concentration of a hypertonic solution?
A hypotonic solution is one in which the concentration of solutes is greater inside the cell than outside of it, and a hypertonic solution is one where the concentration of solutes is greater outside the cell than inside it.
Is the solute concentration high or low in a hypotonic solution?
In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic.
What happens in a hypertonic solution?
In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.
What happens in a hypotonic solution?
In a hypotonic solution, the solute concentration is lower than inside the cell. The prefix hypo means under or below in Latin. Under these conditions, the osmotic pressure gradient forces water into the cell. Depending on the amount of water that enters, the cell may look enlarged or bloated.
When a cell is put in a solution of higher concentration?
If a cell is placed in such a solution which has higher concentration of solute i.e., hypertonic solution, then the water moves out of the cell i.e., exosmosis occurs. As a result cell shrinks.
When a cell is placed in a hypertonic solution?
When a cell placed in hypertonic solution (has more solutes that cell), the cell will shrink because water moves out, firstly from the cytoplasm and then from the vacuole. This process is called as exosmosis which leads to the plasmolysis.
When the concentration of solutes is greater outside the cell than inside?
A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell.
What is the difference between hypertonic solution and hypotonic solution?
1. Hypotonic solutions have less solutes and more solvent while hypertonic solutions have more solutes and less solvent. 2. Hypotonic solutions cause the cell to swell because it promotes shifting of water into it while hypertonic solutions cause the cell to shrink because it pulls the water out of the cell.
What is hypertonic vs hypotonic?
Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood.
Does hypertonic shrink or swell?
A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.
Does hypertonic shrink or swell?
A cell placed in a hypertonic solution will shrink. A hypertonic solution has more solute than the cell. This means that water will flow out of t...
What are hypotonic and hypertonic solution?
A hypotonic solution is one that has less solute and more water compared to the cell. A hypertonic solution is the opposite. A hypertonic solutio...
What is an example of a hypotonic solution?
An example of a hypotonic solution is distilled water. Distilled water is pure water and contains no solute, thus it is hypotonic to cells.
What are hypotonic solutions?
A hypotonic solution is one that has a lower concentration of solute and a greater concentration of water compared to the cell. Cells that are pla...
What is a hypertonic solution?
Hypertonic Solution Definition. A hypertonic solution contains a higher concentration of solutes compared to another solution. The opposite solution with a lower concentration is known as the hypotonic solution. Scientists must describe cell contents compared to the environment. If a cell is placed in a hypertonic solution, ...
What is the term for a cell that is placed in a hypertonic solution?
Scientists must describe cell contents compared to the environment. If a cell is placed in a hypertonic solution, the cell is considered hypotonic.
How does the osmolarity of the roots affect the plant?
By increasing the osmolarity of their roots, the plants are able to change from a hypotonic environment inside the cell compared to the environment, to a hypertonic solution in the cytosol. This lowers the water potential of the root cells and allows water to enter the cells. The cells either store the excess salts in the roots or transport ...
Why are isotonic solutions important?
Isotonic solutions have equal concentrations, although they may have different volumes. This movement of ions and water is extremely important to cells. Cells use ion gradients for a number of purposes. For example, plant cells use a hypertonic solution within their central vacuole to help draw water into the vacuole.
Why is the cytosol hypertonic?
The cell must use energy to actively move solutes into and out of the cell. Too many solutes and the cytosol will become a hypertonic solution compared to the environment. Cells without cell walls can burst in this condition. Too few solutes in the environment will become the hypertonic solution.
How do plants live in a hypertonic environment?
Generally, plants prefer to live in hypotonic environments. In a hypotonic environment, water easily floods plant cells and they can remain turgid, or rigid, due to pressures exerted on their cell walls by the influx of water . The plants use this water potential to give their bodies structure and move water from the roots to the top of the plant. However, many plants have adapted to live in hypertonic environments. Marshes by the sea, mangrove swamps, and other brackish waters contain a much higher salt content than fresh water. The soil becomes saturated with these salts, creating a much higher solute concentration in the soil.
Why do plants use hypertonic solutions?
For example, plant cells use a hypertonic solution within their central vacuole to help draw water into the vacuole. This expands the chamber and allows plants to create turgor pressure in their cells. Animal cells, especially nerve cells, rely on a hypertonic solution and the ions in it to create an action potential or nerve signal.
What is a hypertonic solution?
In other words, a hypertonic solution is one in which there is a greater concentration or number of solute particles outside a membrane than there are inside it.
How does water move in hypertonic solutions?
Movement of Water in Hypertonic Solutions. Water moves across a semipermeable membrane. Remember, water moves to equalize the concentration of solute particles. If the solutions on either side of the membrane are isotonic, water moves freely back and forth.
What are some examples of hypertonic cells?
Hypertonic Example. Red blood cells are the classic example used to explain tonicity. When the concentration of salts (ions) is the same inside the blood cell as outside of it, the solution is isotonic with respect to the cells, and they assume their normal shape and size. If there are fewer solutes outside the cell than inside it, ...
Why is salt water hypertonic?
It's also a problem if you drink too much water . If there is a higher concentration of solutes outside of the cell than inside it, such as would happen if you placed red blood cells in a concentrated salt solution, then the salt solution is hypertonic with respect to the inside of the cells . The red blood cells undergo crenation, which means they ...
Which side of the membrane does water move from?
Water moves from the hypotonic (less concentrated) side of a membrane to the hypertonic (less concentrated) side. The direction of the flow continues until the solutions are isotonic.
Why do cells swell and burst?
The cells swell and may burst as water rushes into the cell to attempt to make the concentration of the interior and exterior solutions the same. Incidentally, since hypotonic solutions can cause cells to burst, this is one reason why a person is more likely to drown in fresh water than in salt water.
Is salt water hypertonic or hypotonic?
But, if you view the situation from the inside of the cell, you could consider the plasma to be hypotonic with respect to the saltwater.
What is it called when a solution is hypertonic?
In the context of biology, when two aqueous solutions are separated by a cell membrane, if the concentration of solute is greater outside the cell than inside the membrane, the solution is called hypertonic. Thus, hypertonicity refers to a relative difference between the concentration of solute inside a cell and the concentration ...
What happens when a cell is placed in a hypertonic solution?
When a cell is placed in a hypertonic solution, osmotic pressure will force water out of the cell to balance the concentration of solute across the membrane. Since water tends to flow out of the cell, cells placed in a hypertonic solution will shrink.
What is hypertonic solution?
Alex Bolano on December 12, 2018 Leave a Comment! A hypertonic solution refers to a solution that has a greater concentration of solute than another solution. In the context of biology, when two aqueous solutions are separated by a cell membrane, if the concentration of solute is greater outside the cell than inside the membrane, ...
What is the tonicity of a solution?
The tonicity of a solution refers to the direction and magnitude of the osmosis of water. In the presence of a semipermeable membrane, water has a tendency to diffuse from regions of low solute concentration to regions of high solute concentration. So, if a cell is placed in salt water, water will move out of the cell into the salt water.
Why does water move out of a cell?
So, if a cell is placed in salt water, water will move out of the cell into the salt water. Conversely, if a cell is placed in fresh water, water will flow into the cell, as the cell has a higher concentration of solute. This movement is due to the diffusion of water from regions where itself is highly concentrated (in low solute concentrations), ...
Why does water expand in an isotonic solution?
Since water is entering the cell, it expands. An isotonic solution has an equal solute concentration to that of the cell. When a cell is placed in an isotonic solution since the solute concentration is equal, water will flow into the cell at the same rate it will leave the cell. The result is that there is no net movement of water molecules.
How to see if corn syrup is hypertonic?
In fact, one can use corn syrup to easily see the effect of hypertonic solutions of animal cells. First, grab some eggs and soak them in vinegar for about 24 hours. This will dissolve the shell but leave the outer membrane. Next, fill a bowl with corn syrup and drop the egg in the mixture. Over time, you will see the egg shrink as water leaves the egg and goes into the corn syrup. Eggs are useful for this experiment because eggs are, for all and intents and purposes, a single cell.
How does water move in a hypertonic solution?
Thus, in a hypertonic solution, water leaves the cell and moves to the environment. This causes the cell to shrivel.
What are some examples of hypertonic environments?
Some animals live in extremely hypertonic environments, such as sea turtles. The ocean is made of salt water and is a hypertonic solution compared to cells. Thus, animals that live an entirely marine life must have strategies for keeping their internal state in homeostasis.
What are the two types of solutions?
There are three main types of solutions: Hypotonic solutions contain a lower concentration of solute compared to the cell. This causes water to rush into the cell and creates an effect opposite of hypertonic solutions. Isotonic solutions are those that have the same concentration of solution compared to the cell.
What is the best solution for plant cells?
There are other types of solutions as well, including: Hypotonic: This solution occurs when the environment has less solute than the cell. It causes water to move into the cell and is the optimal solution for plant cells. However, animal cells can burst, or lyse.
What are the two mechanisms of transport?
Mechanisms of transport: tonicity and osmoregulation. Tonicity is the type of solution that a cell experiences in the extracellular environment, and osmoregulation is how cells deal with changes in tonicity .
How does water move through a cell?
Solutions surround a cell, which is contained by a semipermeable membrane. Based on the type of solution, water moves into or out of the cell through osmosis. In osmosis, water moves from an area of lower solute concentration to an area of higher solute concentration.
What is a solution made of?
A solution is a mixture made of a solute, which is the substance being dissolved, and a solvent, which the substance that does the dissolving. There are many examples of solutions, including lemonade, saline solution for intravenous injections, glucose solutions used to feed cells grown in a laboratory, and more.
What is the difference between a hypertonic and a hypotonic solution?
The difference between hypertonic and hypotonic solution is mainly due to the factors like: A hypertonic solution has a high solute concentration, whereas hypotonic solution has a low solute concentration. The concentration of the solvent is low in the hypertonic solution and high in the hypotonic solution.
What is hypertonic solution?
It is defined as the solution with a high solute concentration outside than the fluids inside the cell, and a high water concentration inside the cell than the surrounding fluid. Hypertonic solution results in cell crenation or contraction.
What happens to water in a hypotonic solution?
Hypotonic solution: From the second solution, water will move from the higher concentration of water in a solvent to the lower water concentration in the solute through a semipermeable membrane of the cell, to maintain the equilibrium.
What is the solute concentration of the first solution?
The solute concentration of the first solution is 30% with a solvent concentration of 60% NaCl.
How does hypertonic and hypotonic solution affect the cell?
Effect on the Cell. The hypertonic and hypotonic solution affect the cell by changing its structural configuration. In a hypertonic solution, the cell shrinks because of the high concentration of water inside the cell. Therefore, water will move out from the cell into its surroundings to maintain the equilibrium both outside and inside the cell.
What are hypertonic and hypotonic solutions based on?
Both the hypertonic and hypotonic solutions are based on the concept of tonicity and osmosis. By knowing the concept of tonicity and osmosis , we can understand the general idea about the direction and extension of the water movement in the solution.
What is tonicity in water?
Tonicity can be defined as the phenomena that govern water flow through a semipermeable membrane through the relative concentration of solutes mixed in the solution. To know the difference in the tonicity of the hypertonic and hypotonic solution, let’s take an example of three different solutions with different solute-solvent concentration.
What is the meaning of the term "hypertonic"?
Hyper means more, meaning that the solution that the cell is placed in contains more solute than the solution inside of the cell.
What is an isotonic solution?
An isotonic solution is a solution in which the same amount of solute and solution is available inside of the cell and outside of the cell. The solution and solute percentage are the same inside the cell as it is in the solution outside of the cell. Therefore, using the numbers above, a cell placed in a solution of water with 0.9% NaCL is in equilibrium. Thus, the cell remains the same size. The solution is isotonic in relation to the cell.
What is the suffix for hypertonic?
The suffix -tonic is in relation to the amount of solute in the solution. Hyper means more, hypo means below. So a hypertonic solution is a solution which contains more solute than the solution inside of the cell. And a hypotonic solution is a solution which contains less solute than the solution inside of the cell.
What is the solution of a cell with a NaCl concentration?
If a cell with a NaCl concentration is placed in a solution of distilled water, which is pure water with no dissolved substances it, the solution on the outside of the cell is 100% water and 0% NaCl. Inside of the cell, the solution is 99.1% water and 0.9% NaCL. Water, again, goes from a higher concentration to a lower concentration.
What is the difference between hypotonic and isotonic?
If the solution inside of the cell has more solute than the solution outside of the cell, the solution is hypotonic. If the solution outside of the cell contains the same solute as the solution inside of the cell, the solution is isotonic.
What is the solution of NaCl?
The solution inside of the cell is 0.9% NaCl, which means it is 99.1% water. Remember, solution flows from a higher concentration of water to a lower concentration of water. This is to dilute areas of higher solute concentrations, so that equilibrium can be achieved.
Does distilled water cause cell swelling?
So water goes from the distilled water solution to the inside of the cell. As a consequence, the cell swells up and possibly bursts. Thus, putting a cell with solute in a distilled water solution will cause swelling and possible bursting of the cell.
