Calculate the pH of a solution that has [HO-] concentration of 0.0026 mol/L.
Asked by Topperlearning User | 30 Apr, 2015, 11:04: AM
answered-by-expert Expert Answer
[HO-] = 0.0026 = 2.6 x 10-3 M
 [H+] = Kw / [HO-] = 1 x 10-14/ 2.6 x 10-3 M
                          = 3.85 x 10-12 M
pH = - log [H3O+] = 12.58
