Abstract:
Alkaline errors of glass electrodes in isopropanol were obtained from a comparison with the hydrogen electrode. Electrode glasses which show low alkaline errors in water are also more ideal in isopropanol. Univalent metal ions cause larger deviations than bivalent. Hysteresis effects were found in going from alkaline to acid solutions but not for the reverse direction.
