What is an example of a liquid that doesn't mix with water?
I agree with the answer below - oil is one example of a liquid that does not mix. Many other substances (specifically organic ones) also don’t mix with water; they are immiscible. However, the presence of an -OH group, in alcohols, for example allow for hydrogen bonding with water molecules, so do mix.
Why can't immiscible liquids be mixed together?
For immiscible liquids the interactions between the two different styles of molecules are worse than the interactions between both types of like molecules. To mix them you would need to break good intermolecular interactions and get marginal ones in their place. Such a process is like a ball rolling uphill: it simply won’t happen.
Why can’t oil and water mix?
Answer: OIL and water don’t mix because of how their molecules are constructed. Water is what is known as a polar molecule. A water molecule is shaped like a V, with an oxygen atom at the bottom point of the V and a hydrogen atom on each of the two top ends.
Why can’t alcohol and water mix?
Alcohol and water don’t mix because ethyl alcohol molecules are smaller and nonpolar, while water molecules are larger and polar. Hydrocarbons and their derivative or solvents, which include alkanes or paraffin, are also immiscible.
What is the color of dish soap?
Dish soap (blue) Rubbing alcohol. Lamp oil (select a cool color like red) Honey. Honey and corn syrup are resistant to mixing in cold water where the organic liquids move to the bottom of a container with water present. Solubility is increased when water molecules are excited by heating.
Why do salt and water mix?
Salt and water mix because both molecules are polar—like dissolves like. It’s also easy to mix vegetable oil and olive oil, or motor oil and peanut oil . . . but that’s gross. You can do this experiment at home using liquids you find around the house.
What are some examples of insoluble molecules in water?
The classic examples of insoluble in water are the alkanes: long, possibly branched compounds containing only carbon and hydrogen atoms. However, attaching functional groups: phosphate, sulfoxide, ...
Why don't oil and water mix?
Answer: OIL and water don’t mix because of how their molecules are constructed. Water is what is known as a polar molecule. A water molecule is shaped like a V, with an oxygen atom at the bottom point of the V and a hydrogen atom on each of the two top ends.
How many poles does water have?
Water molecules contain 2 poles; +ve and -ve. These charges surround other "impurities" e.g. salt Na+Cl-. The water ions then pull them apart and make it difficult to separate water from salt. Oil is an example of a non-polar molecule and does not split in water. Hence, the water ions remain intact, even if mixed. Since water is denser than oil, it will sink to the bottom and oil left at the top.
What is the opposite of "immiscible"?
When a liquid is soluble in another liquid at all concentrations, it is said to be miscible. The opposite is called immiscible, but in many cases just because something is immiscible doesn't mean it isn't soluble. "Aqueous", being in or of water, is typically regarded to be an antonym of "hydrophobic", water hater.
What is the lack of matter called?
Also, there is the lack of matter, called a vacuum. Think: vacuum of space. There’s no matter/atoms jus
