Question

The solubility of $Hg{I}_2$ in water decreases in presence of $KI$.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is B False

$Hg{I}_2$ forms soluble complex with $KI$

$2KI+Hg{I}_2⟶K_{2}Hg{I}_4$

So solubility of $Hg{I}_2$ in water increases in presence of $KI$.
