Unified pH enables to compare acidities between any given solvent or mixtures thereof. So far only metal solid contact glass electrode half-cells have been used. Three commercial, conventional glass electrode half-cells with inner liquid filling were used to investigate the dependence of the unified pH scale on the different electrodes.
