Abstract
The activity coefficients of calcium chloride in aqueous solutions of the amino acids glycine, β-alanine, γ-amino butyric acid, ε-aminocaproic acid, and glycylglycine have been determined with cells utilizing a calcium ion-exchange electrode. Application of the cross-differential relationship allows a measure of the variation of the salting-in parameter across the series of amino acids. The variation of this parameter is discussed using a semiempirical approach developed earlier.
