Question

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

  1. HCl is highly ionised in solution    
  2. HCl is highly soluble in water    
  3. The solubility product of NaCl is lowered by HCl    
  4. The ionic product of open square brackets N a to the power of plus end exponent close square brackets open square brackets C l to the power of minus end exponent close square brackets exceeds the solubility product of NaCl    

The correct answer is: The ionic product of open square brackets N a to the power of plus end exponent close square brackets open square brackets C l to the power of minus end exponent close square brackets exceeds the solubility product of NaCl
