Answer:
A saturated solution - is a solution that contains the maximum amount of solute that is capable of being dissolved. At 20°C, the maximum amount of NaCl that will dissolve in 100. g of water is 36.0 g. ... When 40.0 g is added, 36.0 g dissolves and 4.0 g remains undissolved, forming a saturated solution.
An unsaturated solution - is a solution that contains less than the maximum amount of solute that is capable of being dissolved. ... If more solute is added and it does not dissolve, then the original solution was saturated. If the added solute dissolves, then the original solution was unsaturated.
A supersaturated solution - is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal.
Explanation: Solutions are described as saturated, unsaturated, or supersaturated, depending on the amount of solute in solution.
