Question

Why pure nacl is percipated whenhcl gas is passed in a saturated solution of nacl

Answer 1

Answer:

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. ... Hence ionisation of NaCl get suppressed and deposition of NaCl takes place
