हिन्दीConcentration of the \( \text{Ag}^+ \) ions in a saturated solution of \( \text{Ag}_2\text{C}_2\text{O}_4 \) is \( 2.2 \times 10^{-4} \text{ mol L}^{-1} \). Solubility product of \( \text{Ag}_2\text{C}_2\text{O}_4 \) is
Correct answer · Option 4
\( 5.3 \times 10^{-12} \)
Explanation
For \( \text{Ag}_2\text{C}_2\text{O}_4 \rightarrow 2\text{Ag}^+ + \text{C}_2\text{O}_4^{2-} \), \( K_{sp} = [ \text{Ag}^+ ]^2 [ \text{C}_2\text{O}_4^{2-} ] = 4s^3 = \frac{[\text{Ag}^+]^3}{2} = \frac{(2.2 \times 10^{-4})^3}{2} = 5.3 \times 10^{-12} \).
