Question

AgCl dissolves in a solution of NH₃, but not in water because

• A. NH₃ is a better solvent than H₂O
• B. Ag⁺ forms a complex ion with NH₃
• C. NH₃ is a stronger base than H₂O
• D. the dipole moment of water is higher than NH₃

Hint:

Ammonia can dissolve silver chloride by forming a complex with silver ions.

Answer 1

The Correct Option is B

Step 1: Solubility of AgCl.
AgCl is insoluble in water but dissolves in ammonia due to the formation of a soluble complex ion \( [Ag(NH₃)₂]^+ \). This occurs because NH₃ acts as a ligand and binds to Ag⁺.

Step 2: Conclusion.
Thus, the correct answer is option (B).

Final Answer: \[ \boxed{\text{(B) Ag⁺ forms a complex ion with NH₃}} \]
