Polarographic determination of hydrogen ion activities. Part IV. Basic solutions containing alkali metal ions

Abstract

Acidity functions of aqueous solutions of potassium and sodium hydroxide, of 0·01M-sodium methoxide in aqueous dimethyl sulphoxide, and of 0·011M-tetramethylammonium hydroxide in aqueous tetramethylene sulphone have been measured electrochemically. It has been shown that the acidity function of tetramethylammonium hydroxide solution measured with a hydrogen electrode is the same as that measured with a glass electrode.
