| Assertion (A): | The solubility of AgCl in \(NH_3 (aq.) \) is higher than that in pure water. |
| Reason (R): | When AgCl dissolves in \(NH_3 (aq.) \), it forms a complex ion \(\left[\mathrm{Ag}\left(\mathrm{NH}_3\right)_2\right]^{+}\), which shifts the solubility equilibrium of AgCl in the forward direction. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
