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.
