what is the molar solubility of Zn^2+ in a solution that is buffered at a pH of 3.00?
The Ksp for Zn(OH)2 is 3x10^-17.
pOH = 14 - pH
= 14 - 3.00 = 11.0
OH- = 10^-pOH
= 10^ -11
Zn(OH)2(s) = Zn2+(aq) + 2OH-(aq)
S 10^-11
Ksp = (Zn2+)*(OH-)^2
= 3*10^-17 = S * ( 10^-11)^2
S = 3* 10^5 M
If you have any questions please comment
If you satisfied with the solution please rate it thanks
