એક અલ્પદ્રાવ્ય ક્ષાર $\mathrm{AB}_2$ માટે , $\mathrm{A}^{2+}$ આયનો અને $\mathrm{B}^{-}$આયનો ની સંતુલન સાંદ્રતાઓ અનુક્રમે $1.2 \times 10^{-4} \mathrm{M}$ અને $0.24 \times 10^{-3} \mathrm{M}$ છે. $\mathrm{AB}_2$ નો દ્રાવ્યતા ગુણાકાર શોધો .

A

 $0.069 \times 10^{-12}$

B

 $6.91 \times 10^{-12}$

C

 $0.276 \times 10^{-12}$

D

 $27.65 \times 10^{-12}$

Solution

$ \mathrm{AB}_{2(\mathrm{~s})} \rightleftharpoons \mathrm{A}_{(\mathrm{aq})}^{+2}+2 \mathrm{~B}_{(\mathrm{aq})}^{-} $

$ \mathrm{K}_{\mathrm{sp}}=\left[\mathrm{A}^{+2}\right]\left[\mathrm{B}^{-}\right]^2 $

$=1.2 \times 10^{-4} \times\left(2.4 \times 10^{-4}\right)^2 $

$=6.91 \times 10^{-12} \mathrm{M}^3$
