摘要：

The stoichiometric acid-base equilibrium constants for cu-alanine in tetraethylamonium iodide-potassium nitrate solutions were determined at a constant ionic strength of 1.4 m at 25 degrees C. The results obtained are discussed on the basis of the Friedman and the Pitzer model for electrolyte mixtures.
