Calorimetric measurements were performed on the heats of solution and of dilution for monovalent chlorides and bromides dissolved in the corresponding liquid nitrates. It is found that all the studied alkali halide-alkali nitrate systems exhibit small positive enthalpies of mixing, with the largest effects observed for the sodium systems. It is suggested that these results may be explained in terms of a packing effect which is due to the repulsion between the second nearest neighbor anion cores. Corresponding data for the silver and thallium salts are more complex.They cannot be explained in terms of the second nearest neighbor interactions.
