How are solutions classified based on the amount of solute given in the solution?
Based on the amount of solute in the given amount of solvent, solutions are classified into the following types:-
1. Unsaturated solution
2. Saturated solution
3. Super saturated solution
1. Unsaturated solution: Unsaturated solution is a solution in which more of the solute can be dissolved at a given temperature. In this, the addition of solute is possible till the solution reaches the point of saturation. E.g. 5g or 10g or 20g of NaCl in 100g water.
2. Saturated solution: A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution. E.g. 36g of NaCl in 100g of water at room temperature forms a saturated solution.
3. Super saturated solution: A solution which has more amount of solute than the saturated solution at a given temperature is called super saturated solution.
