Question

. When you add salt (NaCI) to water it completely ionizes in the solvent.

-If you continue to add salt to the solvent, the salt eventually stops ionizing in the solution. Conceptually explain why this happens.

-If you increase the temperature of the solution a higher amount of salt ionizes in solution. Conceptually explain why this happens.

Answer 1

If we continue to add salt to solvent,at a point of time salt stops ionizing.This is because ,at that point the particular solvent attains a point that is called saturation point.beyond this ,no more solute can be added.

Now, if temperature is increased , kinetic energy of the molecules increases, that allows the solvent molecules to separate the solute more effectively than before, ( molecular attraction between solute and solute weakens).This leads to increase solubility.Hence higher amount of salt can be ionized now.
