At 4oC , ionic product of water (K\(\omega\)) is 10-16 . At this temperature, a solution has pH = 7.5 . The nature of this solution at 4oC will be
1. Acidic
2. Alkaline
3. Neutral
4. Cannot be predicted

Find out the solubility product \(K_{sp}\) of \(Ca \left(OH\right)_{2}\) if the pH of its saturated solution is 9:
| 1. | \(0 . 5 \times \left(10\right)^{- 10}\) | 2. | \(0 . 5 \times \left(10\right)^{- 15}\) |
| 3. | \(0 . 25 \times \left(10\right)^{- 10}\) | 4. | \(0 . 125 \times \left(10\right)^{- 15}\) |
