A chloride salt solution acidified with dil. gives a curdy white precipitate, [A], on addition of . [A] on treatment with gives a clear solution, B. A and B respectively are:
- a
and
- b
and
- c✓
and
- d
and
and
Strategy: Use the solubility rules and coordination chemistry of transition metal halides.
Step 1: Solubility and Reaction Silver chloride is an insoluble white precipitate. However, it dissolves in aqueous ammonia or dilute ammonium hydroxide due to the formation of a soluble coordinate complex.
Step 2: Complex Formation The reaction is: The product is the diamminesilver(I) chloride complex.
