H0 measurements in some salt–acid mixtures of fixed total anion concentration

Abstract

The Hammett acidity function, H₀, is reported for 3 and 6 molal mixtures of perchloric, hydrochloric, and nitric acids with their lithium and sodium salts. As expected theoretically, perchlorate mixtures containing lithium exhibit a much closer proportionality between h₀ and acid content than those containing sodium; but the opposite is true of the chloride and nitrate systems.
