NH₄Cl is preferred to NaCl for the preparation of HCl by the action of concentrated H₂SO₄ because
A.NH₄Cl is not expensive
B.NH₄Cl is very volatile
C.NH₄HSO₄ formed during the reaction is insoluble
D.NH₄HSO₄ formed during the reaction is soluble✓ Correct
Explanation
The reaction for the preparation of HCl is given below- below 200 2 4 4 4 2 4 4 4 . 2 . °C NaCl conc H SO NaHSO HCl NH Cl conc H SO NH HSO HCl → → Here, 4 NaHSO produced is insoluble whereas 4 4 NH HSO is soluble. Therefore, 4 NH Cl is preferred over NaCl .
