摘要：

We determined the stoichiometric equilibrium constants of L-valine in equimolar mixtures of KCl-KBr and KCl-KNO3, as well as those of triethanolamine in KCl-KBr at ionic strengths between 0.1 and 1.5 by means of H+ ion-sensitive combined glass electrodes. The results thus obtained were analysed on the basis of the Pitzer and Guggenheim models for the activity coefficients of the species involved, from which different dependences of the stoichiometric constants on the solution ionic strength were derived.
