The pH of a solution is 5. The [H 3 O + ] and [OH - ] are:

The pH of a solution is a measure of the hydrogen ion concentration, [H+]. A pH of 5 means [H+] = 10^-5 M. The concentration of hydroxide ions, [OH-], can be found using the water dissociation constant (Kw = 10^-14 at 25°C), so [OH-] = Kw / [H+] = 10^-14 / 10^-5 = 10^-9 M.
