When HCl gas is passed through a saturated solution of common salt, pure NaCl is precipitated because

Answer»

HCL is HIGHLY ionised in solution
HCl is highly soluble in WATER
The solubility product of NaCl is LOWERED by HCl
The ionic product of `[Na^(+) ] [Cl^(-) ]` EXCEEDS the solubility product of NaCl
