| Abstract: | We have made calorimetric measurements of the enthalpy of solution of NH4NO3(c, IV) in water at 298 K, where (c, IV) indicates the crystal form of amomonium nitrate that is stable from 256 to 305 K. Results of our measurements have been combined with enthalpy of dilution values from Parker to obtain the standard enthalpy of solution of NH4NO3 (c, IV) in water at 298.15 K to be ΔHo = 25.41 kJ mol?1. |
