A method was established to estimate the pH change of several buffer solutions on freezing by using a combination of pH indicators. Among more than 30 buffer solutions examined, almost half exhibited a pH change in the temperature range between freezing point and 220°K; the results were tabulated. Glycerol was found to suppress the pH changes because of its “salt buffer” effect.
