In a 1.2 M solution of KOH, a strong base, the concentration of hydroxide ions ([OH^-]) is equal to the concentration of KOH, which is 1.2 M. The concentration of hydrogen ions ([H^+]) in such a basic solution can be found using the water dissociation constant (Kw = 1.0 × 10^-14 at 25°C), where Kw = [H^+][OH^-]. Given [OH^-] = 1.2 M, solving for [H^+] gives [H^+] = Kw / [OH^-] = 1.0 × 10^-14 / 1.2 M = 8.3 × 10^-15 M.
