Question

A metallic ion 'M' reacts with chloride ion to form white precipitate which is readily soluble in aqueous ammonia. Identify 'M'?

विकल्प

• Cu²⁺

• Ni²⁺

• Co²⁺

• Ag⁺

Answer 1

Ag⁺ 

Explanation:

Ag⁺ reacts with Cl^– ion to form white ppt.

\[\ce{Ag+ + Cl- -> AgCl (white ppt)}\]

\[\ce{AgCl + NH3 -> \underset{Soluble complex}{[Ag (NH3)2] + Cl-}}\]
