6-2.Equilibrium-II (Ionic Equilibrium)
medium

$25\,^oC$ पर $CuBr$ की विलेयता $2 \times {10^{ - 4}}$ मोल$/$लीटर है तो $CuBr$ के ${K_{sp}}$ का मान होगा

A

$4 \times {10^{ - 8}}$ मोल$^2$ लीटर$^{ - 2}$

B

$4 \times {10^{ - 11}}$ मोल$^2$ लीटर$^{ - 1}$

C

$4 \times {10^{ - 4}}$ मोल$^2$ लीटर$^{ - 2}$

D

$4 \times {10^{ - 15}}$ मोल$^2$ लीटर$^{ - 2}$

Solution

(a) $\mathop {CuBr}\limits_{{K_{sp}}}  \rightleftharpoons  \mathop {C{u^ + }}\limits_{(S)\,\,} + \mathop {B{r^ – }}\limits_{(S)\,\,\,\,} $

${K_{sp}} = {S^2} = {(2 \times {10^{ – 4}})^2} = 4 \times {10^{ – 8}}\,\frac{{mo{l^2}}}{{{l^2}}}$
