Question

Distinguish between the saturated and unsaturated solution at a temperature of ${25}^{\circ }$C using the data given below (Note : Solubility of $NaCl$ is $36g$)
i) $16gNaCl$ in $100g$ water
ii) $36gNaCl$ in $100g$ water

Answer 1

Solubility of $NaCl$ is $36g$, this implies that $36g$ of $NaCl$ is required to reach saturation.

(i) $16g$ of $NaCl$ implies that the solution is not saturated i.e. it is unsaturated solution.

(ii) $36g$ of $NaCl$ implies that the solution is saturated.
