Q. No.At 25°C, the solubility product (\( \mathrm K_{s p}\)) of \(\mathrm{PbBr}_2 \mathrm{}\) is \(8 \times 10^{-5} \text {. }\) If the salt is \(80 \%\) dissociated, what is the solubility of \(\mathrm{PbBr}_2 \mathrm{}\) in mol/L?
| 1. | \(\left[\dfrac{10^{-4}}{1.6 \times 1.6}\right]^{1 / 3}\) | 2. | \(\left[\dfrac{10^{-5}}{1.6 \times 1.6}\right]^{1 / 3}\) |
| 3. | \(\left[\dfrac{10^{-4}}{0.8 \times 0.8}\right]^{1 / 3}\) | 4. | \(\left[\dfrac{10^{-5}}{1.6 \times 1.6}\right]^{1 / 2}\) |

| Assertion (A): | The solubilities of two sparingly soluble salts, Ni(OH)2 and AgCN with Ksp of \(4 \times 10^{-8} ~and~1 \times 10^{-10}~mol/L\) respectively. |
| Reason (R): | AgCN is less soluble than Ni(OH)2 |
| 1. | Both (A) and (R) are correct and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are correct but (R) is not the correct explanation of (A). |
| 3. | (A) is correct but (R) is not correct. |
| 4. | (A) is not correct but (R) is correct. |
