Question

Hydrogen chloride is liberated by the action of H2SO4 on metal and ammonium chlorides.

Answer 1

Hey .

Here is the answer.

If you mix ammonium chloride with dilute sulfuric acid there will not be any effective reaction even if the mixture is heated. You will only get a homogeneous solution containing NH4(+), H(+), Cl(-) and HSO4(-) ions.

But if a mixture of pure (solid) ammonium chloride and concentrated sulfuric acid is heated, hydrogen chloride gas will evolve.

2NH4Cl + H2SO4 = (NH4)2SO4 + 2HCl

The other product will be ammonium sulfate as sulfuric acid displaces hydrochloric acid from the latter’s salt.

Thanks.

Answer:

2NH4Cl + H2SO4 ----> (NH4)2SO4 + 2HCL
