Question

What is the ph of a saturated zinc hydroxide solution

Answer 1

The ph of a saturates zinc hydroxide solution is 8.64

Answer 2

Ksp = 1.2 x 10^-17 = [Zn2+] [OH-]^2
Zn(OH)2 <----> Zn2+ + 2OH-
[Zn2+] = x
[OH-] = 2x
1.2 x 10^-17 = (x) ( 2x)^2 = 4 x ^3
x = 1.4 x 10^-6 M
2x = 2.8 x 10^-6 M
pOH = - log 2.8 x 10^-6 = 5.5
pH = 14 - 5.5 =8.5

i think this is it
