Heats of dilution of concentrated aqueous solutions (4.43 moles-kg−1) of FeCl2 were measured at 15, 25, and 35°C. The heat capacities of these concentrated solutions were also measured at the same temperatures. From these data the partial molal heat capacity, C p2 0 (FeCl2, aq, 298.15°K)=−2.56±30 J−°K−1−mole−1, was calculated. The partial molal heat capacity of Fe2+(aq), −2±30 J-°K−1-mole−1, was correlated with the “correspondence principle” equations of Criss and Cobble.
