The thermodynamically defined quantity ( ) is a useful acidity function for measuring the acidic or basic character of electrolytic solutions. This function can be evaluated from electromotive force data () for cells without liquid junction consisting of one electrode reversible to hydrogen ions and one electrode reversible to chloride ions. The function is given by Summarized in 20 tables, the function has been calculated from emf data recorded in the literature for the hydrogen-silver chloride cell. A consistent set of standard potentials (°) and currently accepted values of the natural constants were used. The tables cover a range of ( ) from 1.6 to 12.5 and a range of temperature from 0 to 95° C. Included are buffer solutions of three different charge types. Ionic strengths vary in the range 0.01 to 0.20. Properties and uses of the acidity function are discussed.
