The heat capacities of aqueous solutions containing the reciprocal system K/Na/Cl/SO4 have been determined in the temperature range 333 - 493 K and for overall concentrations included between 0.5 and 5 molal. Experimental data are compared with those calculated both through, the Pitzer's semiempirical equations, neglecting mixed interactions terms, and through the empirical Young's rule. A fair agreement is observed only for moderate values of T and m, at which the two procedures yield comparable results.
