Abstract

New molar enthalpies of solution of NH₄I in water at 298.15 K were measured in an LKB calorimeter. So as to prevent decomposition of ammonium iodide, hydroxylamine sulfate and sodium hydroxide were added in two different quantities. The molar enthalpies of solution extrapolated to infinite dilution are: (13877 ± 37) J · mol^-1 and (13871 ± 41) J · mol^-1. In the absence of hydroxylamine sulfate and sodium hydroxide, values of (13940 ± 35) J · mol^-1 (Alfa) and (13983 ± 12) J · mol^-1 (Merck) were obtained.
