$M(OH)_2$ ની દ્રાવ્યતા નીપજ $10^{-14}$ છે તો $0.1 \,M$ દ્રાવણ $NH_4OH$ માં $M^{+2}$ ની સાંદ્રતા કેટલી થશે ? જો $NH_4OH$ નું $10$$\%$ આયનીકરણ થાય તો ?

A

$10^{-12}$

B

$10^{-16}$

C

$10^{-14}$

D

$10^{-10}$

Solution

$K_{sp} = [M^{+2}] [OH^-]^2$

$[O{H^ – }] = \frac{{10}}{{100}} \times 0.1 = 0.01;\,\,\,\,\,[{M^{ – 2}}] = \frac{{{K_{sp}}}}{{{{[O{H^ – }]}^2}}} = \frac{{{{10}^{ – 14}}}}{{{{[0.01]}^2}}} = {10^{ – 10}}$
