Pure water has a charge carrier density similar to semiconductors [9] [page needed] since it has a low autoionization, K w = 1.0×10 −14 at room temperature and thus pure water conducts current poorly, 0.055 μS/cm. [10] Unless a large potential is applied to increase the autoionization of water, electrolysis of pure water proceeds slowly ...
