What makes the three different types of electrolytes different from each other?
The difference between strong, weak, and non-electrolytes is how much they dissociate into ions in water. Electrolytes are chemicals that break into ions (ionize) when they are dissolved in water. The positively-charged ions are called cations, while the negatively charged ions are called anions.
What are the three factors that determine how fast a soluble substance will dissolve?
The rate of dissolution, in contrast, is a measure of how fast a solute dissolves in a solvent. There are three factors that affect the rate of dissolution: (1) the surface area of the solute, (2) the temperature of the solvent, and (3) the amount of agitation that occurs when the solute and the solvent are mixed.
Are insoluble ionic compounds strong electrolytes?
Even insoluble ionic compounds (e.g., AgCl, PbSO4, CaCO3) are strong electrolytes, because the small amounts that do dissolve in water do so principally as ions; i.e., there is virtually no undissociated form of the compound in solution.
What is weak electrolyte?
Weak Electrolytes. Weak electrolytes produce few ions when they are soluble in water. They dissociate partially and produce few ions. In a solution of weak electrolytes, there will be dissociated ions as well as the neutral molecules of the substance.
Why are electrolytes important?
Electrolytes are present in our body too. They are needed to maintain the balance inside cells and blood fluids in a healthy body. Electrolyte balance is crucial to maintain the osmotic balance, hence the blood pressure inside the body. Na +, K +, Ca 2+ are important in nerve impulse transmission and muscle contractions. Electrolyte homeostasis is controlled by various hormones in the body. For example, aldosterone, controls the Na + amount. Calcitonin and parathormon hormones play a role to maintain the Ca 2+ and PO 43- balance. The electrolyte levels of the blood are measured to identify certain electrolyte imbalances. Mostly, Na + and K + levels in blood and urine are measured to check the kidney malfunctioning, etc. The normal Na + level in blood is 135 – 145 mmol/L, and the normal K + level is 3.5 – 5.0 mmol/L. Extreme levels of electrolytes in the body can be fatal. Electrolytes are also important in plant bodies. For example, the stomata opening and closing mechanisms by guard cells are controlled by electrolytes (K + ).
What are the functions of electrolytes in plants?
Electrolytes are also important in plant bodies. For example, the stomata opening and closing mechanisms by guard cells are controlled by electrolytes (K + ). Electrolytes are substances that produce ions. These compounds can produce ions when they are in molten stage or when they are dissolved in a solvent (water).
What are the two groups of compounds that are able to conduct electricity?

Can electrolytes conduct electricity?
Because of the ions, electrolytes can conduct electricity. Sometimes there may be solid-state electrolytes. Moreover, some gases like carbon dioxide produce ions (hydrogen and bicarbonate ions) when it is dissolved in water.
What are Weak Electrolytes?
A weak electrolyte is an electrolyte which does not ionize in aqueous solution. The solution will contain both ions and molecules of the electrolyte. Most acids are weak electrolytes except for a few ones. Water and acetic acid are weak electrolytes. Dissolution of a substance in water is not a determining factor of its strength as an electrolyte. It’s mean dissolution and dissociation are not the same phenomena. For example, an acetic acid which is an acid found in vinegar is highly soluble in water. However, most of the acetic acid leftovers intact as its original state rather than its ionized state which is ethanoate. An equilibrium reaction acts a significant role in this. When acetic acid is dissolved in water, it ionizes into hydronium ions and ethanoate, but the equilibrium position is to the left. It means when ethanoate and hydronium ions are formed; they quickly return to the acetic acid and water:

Weak Electrolytes and their Examples
The substances which ionize upto a small extent into ions are called weak electrolytes. The molecules of a weak electrolyte are in equilibrium with its ions in a solution. Therefore, the equation which involves the ionization of weak electrolytes is represented with double-headed arrows, meaning, the reaction is reversible, such as,
Strong Electrolytes and their Examples
The substances which ionize completely into ions are known as strong electrolytes. Here the unionized molecules (electrolytes) are present in such a small amount that they can be neglected. Also, they are not of any significance to study the ionization constant of strong electrolytes.
How to Categorize the Electrolytes
Substances may be categorized as strong, weak, or nonelectrolytes by studying their electrical conductance in an aqueous solution. The solution will conduct electricity if it contains free and charged ions. The nonelectrolytes are out of the discussion here as their aqueous solution would not conduct current due to the lack of charged species.
Concepts Berg
Electrolytes dissociate into ions when added to water. If a chemical is electrolyte it must dissociate whether weak or strong.
What is a weaker electrolyte?
A weaker electrolyte is the one which do not fully dissociate in aqueous solution and most of its molecules remain combined, releasing merely few ions to the solution. The process of electric conduction is relatively slower in weak electrolytes due fewer numbers of mobile ions. Dilute ionic compounds are considered to be weak electrolytes.
What is the term for a substance that allows the flow of electric current through it?
Any substance which allows the flow of electric current through it is known as an electric conductor. However, the term conductor is specifically used for solids and the liquids possessing the similar sort of properties are more appropriately called as electrolytes. Going even deep into the basic definition of electrolytes, these are actually ionic compounds which break down into charged ions when electric current passes through them. Ionic compounds are usually solids and cannot conduct electricity, as there are no free electrons for the conduction purpose. However, then ionic compounds are dissolved in water or melted into their liquid state, they possess mobile ions which have to tendency to carry electrons from one point to the other and hence, conducting electricity very effectively. The strength of electrolytes varies according to their composition and it affects the overall reaction process.
