Ammonium Chloride (NH4CL) is an odorless white powder that reacts explosively with potassium chlorate, bromine trifluoride and ammonium nitrate. Heating Ammonium Chloride is very dangerous as it will decompose into nitrogen oxides, ammonia and hydrogen chloride. Ammonium Chloride is also corrosive to copper. This compound is used commonly in cooling baths, fertilizers and even batteries.
Aluminum Ammonium Sulfate (AlNH4(SO4)2) is an odorless, colorless crystal. Aluminum Ammonium Sulfate is corrosive to metals in the presence of water. When combined with alkalis it will produce ammonia gas. It is used in fast-acting fertilizers, caramel food coloring, and deliming agent in tanning.
Ammonium Carbonate is a strong-smelling crystal or powder that is corrosive to nickel and copper. It is used as a smelling salt, baking soda and in dyeing. It decomposes in air.
