Silver chloride dissolves in aqueous ammonium hydroxide because it leads to the formation of which species?

1. AgOH
2. Ag2O
3. [Ag(NH3)2]+
4. NH4Cl

Correct answer: [Ag(NH3)2]+

Solution

AgCl dissolves in aqueous ammonia by forming the soluble diammine silver(I) complex ion [Ag(NH3)2]+, which shifts the dissolution equilibrium and dissolves the precipitate.
