Which compound is formed when Ammonium hydroxide is added to silver chloride?
Correct answer: A. [Ag(NH3)2]Cl
- A. [Ag(NH3)2]Cl
- B. [Ag(NH3)]Cl
- C. [Ag(NH3)4]Cl
- D. [Ag(NH3)6]Cl
Explanation
When ammonium hydroxide is added to silver chloride, the silver chloride dissolves in the ammonia to form a diamine complex: [Ag(NH3)2]Cl. This occurs because ammonia acts as a ligand, donating a pair of electrons to silver ions, forming a stable complex. The correct option, [Ag(NH3)2]Cl, reflects this complex formation. Other options like [Ag(NH3)]Cl, [Ag(NH3)4]Cl, and [Ag(NH3)6]Cl are incorrect as they suggest incorrect stoichiometries and coordination numbers that do not occur in this reaction.

About Salts and Hydrolysis
Salt hydrolysis explains how ions from weak acids or weak bases react with water and affect the pH of a solution. The content covers acidic, basic and neutral salts, hydrolysis equations, Ka, Kb and Kw relationships, degree of hydrolysis and buffer connections, distinguishing hydrolysis from simple acid-base neutralisation.
