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 5.0 × 10-7 M. The equilibrium constants for the equilibria that occur in the solution follow:
Zn(OH)2 (s) ksp= 3.0*10^16
Zn(OH)+ the B1= 2.5*10^4
Zn(OH)3- the B3= 7.2*10^15
Zn(OH)4 2- the B4= 2.8 *10^15
I need proficient help to working out this problem
