The molar solubility of Zn(OH)2 ….

The molar solubility of Zn(OH)2 in 0.1 M NaOH solution is x×1018M. The value of x is _ _ _ _ . (Nearest integer)

(Given: The solubility product of Zn(OH)2 is 2×1020)

Solution

Zn(OH)2Zn2+s+2OH2s+0.1

Ksp=[Zn2+][OH]2=s.(2s+0.1)2

2×1020=s.(2s+0.1)20.12×s

s=2×1018

x=2
