GENERAL KNOWLEDGE

Detailed explanation-1: -If a solution contains less than the maximum amount of solute, it is unsaturated . When a solution is saturated and excess solute is present, the rate of dissolution is exactly equal to the rate of crystallization (Figure 13.2.

Detailed explanation-2: -An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved.

Detailed explanation-3: -A supersaturated solution is one that has more solute than it can hold at a certain temperature. Typically when the temperature of a solution is increased, more particles can be dissolved, thus increasing the amount of solute.

Detailed explanation-4: -Solubility is a specific amount of solute that can dissolve in a given amount of solvent.
