When HCl gas is passed through a saturated solution of common salt, pure NaCl is precipitated becaus — Ionic Equilibrium Chemistry Question

💡 Solution & Explanation

We know that- NaCl Na Cl HCl H Cl -> -> On passing HCl, the concentration of chloride ions on product side increases. Therefore, to attain IONIC EQUILIBRIUM 46 equilibrium, the reaction proceeds in backward direction. Hence, the ionic product exceeds the solubility product of sodium chloride and, therefore, pure sodium chloride precipitates out from the solution.
