Effect of 'Heating' and 'Cooling' on a Saturated Solution
A solution is 'saturated' at a particular temperature only.So,if a saturated solution at a particular temperature is heated to a higher temperature, then it becomes unsaturated.This is because the solubilityof solute increases on heating and more of solute can be dissolved on raising the temperature of the solution.Please note that the solubility of a solute in a solution, however, cannot be increased indefinitely on raising the temperature of the solution. We will now describe the effect of cooling on a saturated solution. If a saturated solution available at a particular temperature is cooled to a lower temperature, then some of its dissolved solute will separate out in the form of solid crystals. This is because the solubility of solute in the solution decreases on cooling. We will now discuss how a saturated solution can be prepared.
