: Zero-current cell potential measurements were used
to determine the solution activity coefficient in a ternary system
{yKCl + (1 − y) KH2PO4}(aq) at temperature T = 298.15 K. The
cell of the type K−ISE|KCl(mKCl), KH2PO4(mKH2PO4
)|Ag|AgCl was
used in the total ionic strength range, Im = 0.0886−1.0046 mol
kg−1
. In order to generate a set of parameters that can be applied in
a wide range of mixed solution ionic strengths, the Pitzer,
Scatchard, and Clegg−Pitzer−Brimblecombe models were used to
fit all available experimental data, including cell potential and
isopiestic measurements from the literature. The experimental and
calculated values of thermodynamic properties for the studied
system are in excellent agreement. Potential interactions and solution structure were discussed by means of the excess free energy of
mixing via potential pairs, triplets, or quads for the investigated solution using the Scatchard model mixing parameters
