Abstract
Emf measurements were performed on solutions at temperatures from 278.15 to 318.15 K and at eight different ionic strengths from 0.1 to 3.0 mol kg-1, by using a Harned's emf cell without liquid junction of the type Pt;H2(g, 1 atm)|HCl(m1),-NiCl2(m2)|AgCl{A}. From these measurements, the Pitzer mixing coefficients SθH,Ni and ψH,Ni,Cl as well as linear representation of temperature derivatives δSθH,Ni/δT and δψH,Ni,Cl/δT have been determined. The results are interpreted in terms of simple Harned's rule and Pitzer's formalism for mixed electrolyte solutions. The activity coefficients at ionic strength fraction y of NiCl2 at 298.15 are given.
