Question

When HCl gas is passed through a saturated
solution of NaCl, the solubility of NaCl
(a) increases
(b) decreases
(c) does not change
(d) NaCl is decomposed

Answer 1

Answer:

increases is the answer

Answer 2

Answer:

In saturated solution of NaCl,equillibrium is established between ions and unionised NaCl. When HCl gas is passed through saturated solution of NaCl,it is completely dissociated to form H+ and Cl- ions. Cl- ion is common to both electrolyte ,hence Cl- ion concentration in solution increases.
