The salt `Zn(OH)_(2)` is involved in the following two equilibria:
`Zn(OH)_(2)(s) hArr Zn^(2+)(aq) +2 overset(Theta)OH(aq) K_(sp) = 1.2 xx 10^(-17)`
`Zn(OH)_(2)(s)+2 overset(Theta)OH hArr Zn(OH)_(4)^(2-)(aq)K_(f) = 0.12`
Calculate `[overset(Theta)OH]` at which solubility of `Zn(OH)_(2)` is minimum. Also find the solubility of `Zn(OH)_(2)` at this `pH`.
