Equilibrium
Flow will you purify an impure sample of sodium chloride containing water soluble impurities?
A saturated solution of the impure sample is prepared and HCl gas is passed through it.
By passing HCl gas, the concentration of Cl– ion increases. According to Le-Chatelier’s principle, equilibrium shifts to the left. As a result, NaCl(s) will be formed. In other words, we can say that pure NaCl will get precipitated leaving behind the impurities in the aqueous solution.
