The conductances of sodium hydroxide solutions at 15�, 25�, 50�, and 75� have been determined at concentrations up to 0.02N with special precautions to eliminate the effects of carbon dioxide and of alkaline attack on glass cells. The limiting conductances have been determined from the Fuoss-Onsager and Pitts equations, and the mobility of the hydroxide ion calculated. The theoretical specific conductance of water at various temperatures has been calculated.

The ionization ratio of thioacetamide in aqueous sodium hydroxide, determined spectrophotometrically, is proportional to the concentration of hydroxide ion up to a concentration of about 1 M, and indicates a pKHA of 13.4. For more concentrated solutions the ionizing power increases more rapidly than the hydroxide ion concentration; from the experimentally determined ionization ratios the values of the h− acidity function for 1–6 M sodium hydroxide have been calculated. The relation of h− values to the salting-out parameters and water activities of concentrated sodium hydroxide solutions is discussed.
