The solubility of barium sulphate at 298 K is `1.1 xx10^(-5) mol L^(-1)`. Calculate the solubility product of barium sulphate at the same temperature .

Explanation

To calculate the solubility product (Ksp) of barium sulfate (BaSO4) at 298 K, we can follow these steps:

### Step 1: Write the Dissociation Equation
Barium sulfate dissociates in water according to the following equation:
\[ \text{BaSO}_4 (s) \rightleftharpoons \text{Ba}^{2+} (aq) + \text{SO}_4^{2-} (aq) \]

### Step 2: Define Solubility
Let the solubility of barium sulfate be represented by \( S \). According to the problem, the solubility \( S \) is given as:
