Question

The solubility product of $H{g}_2{I}_2$ is equal to

• A. $[H{g}_2^{2+}][I^{-}]$
• B. $[H{g}^{2+}][I^{-}]$
• C. $[H{g}_2^{2+}]{[I^{-}]}^2$
• D. $[H{g}^{2+}]{[I^{-}]}^2$

Answer 1

Answer: (C)

$H{g}_2{I}_2(s)\rightleftharpoons H{g}_2^{2+}+2I^{-}$
$\therefore$ $K_{sp}=[H{g}_2^{2+}]{[I^{-}]}^2$
