Abstract

The determination of the liquid‐junction potential at the interface of an oxalate and a succinate buffer solution of known pH* in water, methanol or a methanol‐water mixture and a saturated KCl solution in water at 25° is described. When the pH* of such a solution is measured by means of a pH meter standardized by an aqueous standard solution, this liquid‐junction potential causes an error of over 2 pH* when the methanol content of the solution is high.

## Abstract It has been shown that pH\* values, determined by the electrometric method in solvents other than water, can be interpreted as ‐log __m__~H~γ\*~H~ if the pH meter is standardized by means of a standard solution in the same solvent.
