The solubilty of barium sulphate at 298 K is `1.1 xx 10^(-5) "mol " L^(-1)`. Calculate the solubilty product of barium sulphate at the same temerature.

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:
\[ \text{BaSO}_4 (s) \rightleftharpoons \text{Ba}^{2+} (aq) + \text{SO}_4^{2-} (aq) \]
