The values of Ksp of two sparingly soluble salts Ni(OH)2 and AgCN are 2.0 × 10–15 and 6 × 10-17 respectively.
The more soluble salt is:
1. Ni(OH)2 is more soluble than AgCN
2. AgCN is soluble in than Ni(OH)2
3. Both have similar solubility
4. None of the above
The molar solubility of Ni(OH)2 in a solution containing 0.10 M NaOH, given that the ionic product of Ni(OH)2 is 2.0 × 10–15, is:
1. | 2.0 × 10–13 M | 2. | 2.0 × 10–12 M |
3. | 2.0 × 10–11 M | 4. | 2.0 × 10–16 M |
