AMMONIUM SULFITE chemical Properties,Uses,Production

Chemical Properties

Colorless to white crystals that space soluble in water (NH4)2S03H20 is offered both as a to reduce agent and also in photography. This compound is a salt the can kind from the reaction the ammonia and sulfur dioxide or hydrogen sulfide. This product is typically found in the overhead of crude oil distillation units and can be rather corrosive to steel equipment. Chemistry corrosion inhibitors are regularly used to manage corrosion indigenous ammonium sulfite and also other ammonium salts

Chemical Properties

Ammonium sulfite is a colorless to yellow crystalline(sand-like or sugar-like) solid, generally sold or usedin a 40% solution.

General Description

AMMONIUM SULFITE is a colorless crystalline solid. The major hazard is the risk to the environment. Immediate steps should be required to limit its infect the environment. AMMONIUM SULFITE is provided in the manufacture of other chemicals, in medicine, and also photography.

Air & Water Reactions

dissolve in water.

Reactivity Profile

AMMONIUM SULFITE is a to reduce agent. Emits toxic sulfur dioxide and also oxides the nitrogen when heated come decomposition .

Health Hazard

Inhalation the dust reasons irritation that nose and throat. Ingestion causes irritation the mouth and also stomach. Dust irritates eyes.

Fire Hazard

Special perils of burning Products: toxicity sulfur dioxide and oxides that nitrogen may form in fires.

Potential Exposure

Ammonium sulfite is provided in medicines,metal lubricants; explosives, photography, hair wavesolutions; and also to make various other chemicals. The is additionally used as apreservative, and for treating farming grain.


UN2693 Bisulfites, inorganic, aqueous solutions,n.o.s., risk class: 8; Labels: 8-Corrosive material.UN3077 Environmentally hazardous substances, solid, n.o.s., risk class: 9; Labels: 9-Miscellaneous hazardousmaterial, technical Name Required.


A solid reducing agent. Reacts violentlywith strong oxidizers (chlorates, nitrates, peroxides,permanganates, perchlorates, chlorine, bromine, fluorine,etc.); contact may reason fires or explosions. Keep awayfrom alkaline materials, solid bases, strong acids, oxoacids,epoxides.

Waste Disposal

Dissolve or mix the materialwith a combustible solvent and also burn in a chemical incineratorequipped through an afterburner and scrubber. Every federal,state, and local environmental regulations need to beobserved. Might be buried in a chemistry waste landfill inaccordance through federal, state, and local statutes; or, if oxidizedand neutralized, it might be sent out to a municipal sewagetreatment plant for biological treatment Incineration.
