Question
Explain the following giving examples. Saturated solution.
✓
Answer
A saturated solution is a solution in which the maximum amount of solute has been dissolved at a given temperature. The solution cannot dissolve beyond that amount of solute at that temperature. Any more solute added will settle down at the bottom of the container as a precipitate. Suppose 500g of a solvent can dissolve a maximum of 150g of a particular solute at 40°C. Then, the solution obtained by dissolving 150g of that solute in 500g of that solvent at 300K is said to be a saturated solution at 300K.
