Abstract : In determining the activity coefficients of electrolytes in aqueous solutions from the freezing point to the boiling point of the solvent, various equations have been used in the treatment of the data. This paper gives values for activity coefficients of electrolytes of various valence types from 0 to 100 C, and for ionic strengths from zero to 0.1 molal or 0.1 molar, as calculated by seven different equations based on the theory of interionic attraction. These equations are those of Debye and Huckel, Guntelberg, Davies, Scatchard, and Bjerrum, and what may be termed an extended Guntelberg equation and an extended Scatchard equation. (Author)
