PHYSICAL AND CHEMICAL PROPERTIES Molecular Weight: 53.50 Solubility in water: 20% at -13°C, 25% at 10°C, 30% at 33°C, 40% at 83°C Strongly endothermic (lowers solution temperature upon dissolving). Aqueous solubility suppressed by sodium chloride. Slightly soluble in methyl and ethyl alcohol and acetone. Fair solubility in glycerine. Melting Point: Sublimes. pH of Solutions: 25°C: 1% 5.5, 3% 5.1, 10% 5.0 (technical grade). Appearance: White crystals, practically 100% will pass through a No. 20 screen. Reactions: Decomposed in solution by strong alkalies to liberate ammonia Reacts with nitrites to form nitrogen. Reported to reduce oxides of cobalt and nickel at high temperatures. Hydrox- ides of nickel, zinc, cadmium and manganese reported to be more soluble in water in presence of ammonium chloride. Acid characteristics cause acceleration of set of urea-formaldehyde resins. Quality: Principal impurity is sodium chloride. Very low in metallic impurities. Technical grade better than 99% NH4CI.
