Electromotive force measurements of cells without liquid-junction containing hydrogen electrodes and silver – silver chloride electrodes have been used to derive the dissociation constants of acetic acid and solvent water – ethylene glycol mixtures (50 and 70 mass % of ethyleneglycol) at 14 temperatures from −35 to 30 °C. Primary acidity standards related to these acetic buffered and sodium hydroxide solutions are given.
