  1. [H+] [OH-] = Kw / [H+] [OH-] [H+]>[OH-] [H+]<[OH-] [H+]=[OH-] Acidic Solution Basic Solution Neutral Solution What are the concentrations of H+ and OH- in a 0.0012 M NaOH solution? Answer: NaOH s completely dissociated: 0.0012 M NaOH (ac)  0.0012 M Na+(ac) + Substituting [OH]- in the Kw equation: Kw = 1x10-14 = [H+][OH-] 1x10-14 = [H+](0.0012) [H+] = 1x10-14/0.0012 = 0.0012 M OH- (ac) 8.3x10-12 M
