$H g C l_{2}$ and $I_{2}$ both when dissolved in water containing $I^{-}$ ions the pair of species formed is:NEET 2017

Options:

Answer:

Solution:

In Solution containing $H g C l_{2}, I_{2}$ and $I^{-},$ both $H g C l_{2}$ and $I_{2}$ compete for $I^{-} .$

$\begin{matrix} H g C l_{2} + 2 I^{-} & \to & H g I_{2} ↓ & + & 2 C l^{-} \\ Red ppt \end{matrix}$

$\begin{matrix} H g I_{2} + 2 I^{-} & \to & {[H g I_{4}]}^{2 -} \\ soluble \end{matrix}$

$I_{2} + I^{-} \to I_{3}^{-}$
