Distinguish between the following pair of compounds using a reagent as a chemical test: Ammonium sulphate crystals and sodium sulphate crystals.

Ammonium sulphate crystals can be distinguished by sodium sulphate crystals by calcium oxide. Ammonium sulphate on reaction with calcium oxide liberates ammonia gas that on reaction with hydrochloric acid gives ammonium chloride. But sodium sulphate does not react with calcium oxide.

Complete the following chemical equations : NH 3 + 3 Cl 2 Excess → ______ + 3 HCl

Chlorine reacts with ammonia in two ways depending upon the quantity of ammonia. Therefore, the following chemical reaction will take place when ammonia is treated with excess of chlorine to form nitrogen trichloride and hydrochloric acid- NH 3 + 3 Cl 2 Excess → NCl 3 + 3 HCl
