Question

______ is a white precipate soluble in excess of NH₄OH.

विकल्प

• AgCl

• PbCl₂

Answer 1

AgCl is a white precipate soluble in excess of NH₄OH.

Explanation:

Silver chloride (AgCl) forms a white precipitate that dissolves in excess ammonium hydroxide (NH₄OH) because it reacts to form a soluble coordination complex called diamminesilver(I) chloride. In contrast, lead chloride (PbCl₂) remains insoluble as it does not form a similar soluble complex with ammonia.
