Question

Ammonium chloride can be prepared by treating two gases together.
(a) Name the two gases?
(b) Which one of the above two gases is used for the preparation of fertilizers?
(c) How will you prepare calcium chloride $\left(CaC{l}_2\right)$ by using ammonium chloride?

Answer 1

(a) Ammonia $\left(N{H}_3\right)$ and Hydrogen chloride $\left(HCl\right)$
(b) Ammonia $\left(N{H}_3\right)$
(c) Calcium chloride $\left(CaC{l}_2\right)$ can be prepared by heating a mixture of ammonium chloride and calcium hydroxide. The chemical equation is as follows:
$2N{H}_{4}Cl+Ca(OH{)}_2\to 2N{H}_3+CaC{l}_2+2H_{2}O$
