A chloride which forms a precipitate that is soluble in excess of ammonium hydroxide is:

• A. Calcium chloride
• B. Ferrous chloride
• C. Ferric chloride
• D. Copper chloride

Answer 1

The correct option is D

Copper chloride

Copper chloride (${\mathrm{CuCl}}_2$) reacts with ammonium hydroxide (${\mathrm{NH}}_4\mathrm{OH}$) to give a pale blue precipitate which dissolves in excess of ammonium hydroxide (${\mathrm{NH}}_4\mathrm{OH}$) to give a deep blue solution.

The correct option is (d) Copper chloride here.
