Problem- Determine the concentrations of each zinc-containing species in a solution saturated with solid Zn(OH)2 and having a fixed OH- concentration of 3.7 x 10-7 M. The equilibrium constants for the equilibria that occur in the solution follow:
Zn(OH)_2 (s) Ksp = 3.0 x 10-16
Zn(OH) B1 = 2.5 x 10^4
Zn(OH)_3- B3 = 7.2 x 10^15
Zn(OH)^4^2- B4 = 2.8 x 10^15
I found Zn on my own Zn2+ = 2,2 x 10^-3 M
I can't find
Zn(OH)+
Zn(OH)_3
Zn(OH)_4^2-
