यदि $M{X_2}$ प्रकार के वैद्युत अपघट्य की विलेयता $0.5 \times {10^{ - 4}}$ मोल$/$लीटर है, तो इस विद्युत अपघट्य के ${K_{sp}}$ का मान होगा

A

$5 \times {10^{ - 13}}$

B

$25 \times {10^{ - 10}}$

C

$1.25 \times {10^{ - 13}}$

D

$5 \times {10^{12}}$

(AIPMT-2002)

Solution

(a) $M{X_2} \rightleftharpoons  \mathop {{M^{2 + }}}\limits_{(S)\,\,\,\,\,\,} + \,\mathop {2{X^ – }}\limits_{{{(2S)}^2}\,\,} $;

$4{S^3} = 4 \times {(0.5 \times {10^{ – 4}})^3}$
$ = 5 \times {10^{ – 13}}$
