Calculate the [H3O+] in 0.030M Mg(OH)2.
Solution
Mg(OH)2 is a strong base
Mg(OH)2 ------------- Mg+2 + 2 OH-
concentration of Mg(OH)2 = 0.030M
[OH-] = 2x0.030= 0.060M
[H3O+][OH-] = Kw where Kw = ioinc product of warer= 1.0x10^-14M2
[H3O+] = Kw/[OH-]
[H3O+] = 1.0x10^-14/0.060 = 16.67 x10^-14M
[H3O+] = 1.67x10^-13M
