The solubility of BaSO4 in water is g/ litre at 298 K. The value of the solubility product will be: (Molar mass of BaSO4 = 233 gmol–1)
1. | 1.08 × 10–10 mol2 L–2 | 2. | 1.08 × 10–12 mol2 L–2 |
3. | 1.08 × 10–14 mol2 L–2 | 4. | 1.08 × 10–8 mol2 L–2 |
Assertion (A): | Sparingly soluble salts AB and XY2 with the same solubility product, will have different solubility. |
Reason (R): | Solubility of sparingly soluble salt depend upon solubility product as well as the type of salt. |
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. |
