GENERAL KNOWLEDGE

Detailed explanation-1: -The solution which contains more solute than that could be dissolved by the solvent under normal conditions is known as an unsaturated solution.

Detailed explanation-2: -Supersaturated solutions, which contain more dissolved solute than allowed under particular conditions, are not stable; the addition of a seed crystal, a small particle of solute, will usually cause the excess solute to crystallize.

Detailed explanation-3: -In an unsaturated solution, the solute will simply dissolve. In a supersaturated solution, the solution is unstable-so the addition of more solute would cause the dissolved solute to crystallize.

Detailed explanation-4: -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-5: -Solution which contains maximum possible amount of solute at any given temperature is called a saturated solution. At any particular temperature, a solution that has dissolved as much solute as it is capable of dissolving, is said to be a saturated solution.
