Question

If $K_{sp}$ of $H{g}_2{I}_2$ is $3.2\times 10^{-23}$ then its solubility will be

• A. $4\times 10^{-8}$
• B. $2\times 10^{-8}$
• C. $3.2\times 10^{-6}$
• D. $5\times 10^{-7}$

Answer 1

Answer: (B)

$H{g}_2{I}_2(aq)$ $\rightleftharpoons$􏰇􏰇􏰇 $H{g}_2^{2+}$(aq) + $2I^{-}(aq)$
Here, $K_{SP}=4s^3$
