$BaCl_2$ નો દ્રાવ્યતા ગુણાકાર $4\times10^{-9}$ છે. તો તેની દ્રાવ્યતા મોલ/લિટરમાં .......

A

$1 \times10^{-3}$

B

$1 \times10^{-9}$

C

$4 \times10^{-27}$

D

$1 \times10^{-27}$

Solution

${K_{sp}} = 4{S^3},\,\,\,{S^3} = \frac{{4 \times {{10}^{ – 9}}}}{4} = {10^{ – 9}}$

$\therefore \,\,\,S = {10^{ – 3}}M$
