摘要：

The activity coefficients of calcium chloride in aqueous solutions of the amino acids glycine, beta-alanine, gamma-amino butyric acid, epsilon-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 semiempirieal approach developed earlier.
