Question
What is the expression for $\mathrm{K}_{\mathrm{sp}}$ of $\mathrm{Ag}_2 \mathrm{CrO}_4$ ?
✓

Answer

$\text{Ag}_2\text{CrO}_4(\text{s})\rightleftharpoons2\text{Ag}^+(\text{aq})+\text{CrO}_4^{2-}(\text{aq});$
$\text{K}_{\text{sp}}=[\text{Ag}^+]^2[\text{CrO}_4^{2-}]$
$\because[\text{Ag}_2\text{Cr}_2\text{O}_4(\text{s})]=1.$
