Solubilities of ammonium Iodide and ammonium bromide In liquid ammonia were determined In the temperature range 270.0-350.0 K. Solubilities of these solutes In liquid ammonia Increased with the temperature, and the values of weight percent solubility increased from 77.34 to 83.01 wt % for ammonium Iodide, and from 88.71 to 73.19 wt % for ammonium bromide. Solubilities of the mixtures of ammonium Iodide and ammonium bromide (four weight ratios of NH4I/NH4Br = 0.37, 0.80, 1.48, and 2.95) In liquid ammonia were also determined In the temperature range 270.0-350.0 K. The relation between temperature and weight percent solubility for ammonium Iodide In liquid ammonia was shown by a smooth curve, but a bend point appeared on the solubility curve for ammonium bromide or Its mixture with ammonium Iodide In liquid ammonia. With increasing weight ratios of ammonium Iodide to ammonium bromide, the bend point on the solubility curve gradually moved toward lower temperature.
