Vedclass · Answer

(C) When $HCl$ gas is passed through a saturated solution of $NaCl$,the concentration of $Cl^-$ ions increases significantly due to the dissociation of $HCl$ $(HCl \rightleftharpoons H^+ + Cl^-)$.According to the common ion effect,the increase in the concentration of $Cl^-$ ions shifts the equilibrium of $NaCl$ $(NaCl \rightleftharpoons Na^+ + Cl^-)$ to the left.This causes the precipitation of pure $NaCl$ from the solution,as the solubility product $(K_{sp})$ of $NaCl$ is exceeded.

Pure $NaCl$ is prepared by passing $HCl$ gas through a saturated solution of common salt in water. The principle used is:
