6-2.Equilibrium-II (Ionic Equilibrium)
medium
$M(OH)_2$નો $K_{sp}$ $3.2\times10^{-11}$ છે. પાણીમાં સંતૃપ્ત દ્રાવણની $pH$ ......
A
$3.40$
B
$10.30$
C
$10.60$
D
$3.70$
(AIIMS-2014)
Solution
${K_{sp}} = 4{S^3} = 3.2 \times {16^{ – 11}}$ $\therefore \,S = 2 \times {10^{ – 4}}\,M$
$[O\bar H] = 2S = 2 \times 2 \times {10^{ – 4}}\,M$
$\therefore \,pH = 14 – pOH$
$ = 14 + \log \,4 \times {10^{ – 4}} = 10.60$
