| | Ammonium sulfite monohydrate Usage And Synthesis |
| Chemical Properties | colorless crystal(s); loses H2O and gradually oxidizes to (NH4)2SO4 when heated in air; hygroscopic; used in medicine, metal lubricants, as a chemical reducing agent [MER06] [HAW93] | | Physical properties | White or pale yellow solution. Thermal decomposition. Soluble in water, slightly soluble in ethanol, hardly soluble in acetone. The relative density of the saturated solution is 1.1995 (20°C), which is alkaline. Strong corrosion to steel. | | Uses | Ammonium sulfite monohydrate is used in caramel coloring in the food industry. It is also used in cosmetics as a hair straightening agent and a hair waving agent. It acts as a reducing agent in photography. Further, it is used in the production of bricks in order to use in blast furnace linings. In addition to this, it used in gas scrubbers. | | Uses | Ammonium Sulfite is an additive used in the production of
caramel. | | Precautions | Air sensitive. Incompatible with strong oxidizing agents, ammonia and acids. |
