Abstract
Heats of dilution have been measured for aqueous solutions of tetramethylguanidinium perchlorate and chloride and for tetramethylammonium nitrate at 25°C. Excess enthalpies have been calculated and combined with excess free energy data which were previously published to yield excess entropy. These results furnish further evidence for the association of the tetramethylguanidinium salts in aqueous solutions.
