Question
Differentiate between a saturated and an unsaturated solution. How will you test whether a given solution is saturated or not?
✓

Answer

A solution in which no more solute can be dissolved at that temperature is called a saturated solution while a solution in which more quantity of solute can be dissolved without raising its temperature is called an unsaturated solution. To test the saturation or unsaturation of a solution, more solute may be added to the solution. If that solute gets dissolved in the solution then the solution will be unsaturated. To test whether a given solution is saturated or not, add some more solute to the solution and try to dissolve it by stirring. If solute does not dissolve in the given solution, then it will be a saturated solution.

One of the forms of a naturally occurring solid compound $P$ is usually used for making the floors of houses. On adding a few drops of dilute hydrochloric acid to $P,$ brisk effervescence are produced. When $50g$ of reactant $P$ was heated strongly, than $22g$ of a gas $Q$ and $28g$ of a solid $R$ were produced as products. Gas $Q$ is the same which produced brisk effervescence on adding dilute $\text{HCl}$ to $P.$ Gas $Q$ is said to cause global warming whereas solid $R$ is used for white$-$washing.
