摘要：

A systematic study of the dependence of acid-base stoichiometric constants on the ionic strength has been carried out for the aminoacid L-valine in ClK and BrK solutions. The observed dependence has been interpreted by using Guggenheim, Scatchard and Pitzer models for the activity coefficients of the species involved in the equilibria.
