sodium sulfite - (sodium sulphite, disodium salt of sulfurous acid) is, depending on the grade, powder of white or yellowish. Soluble in water. Fire - and explosion - proof. Not flammable.
Sodium sulfite (sodium sulphate) is an important product of the chemical industry. It is widely used both in the chemical industry and other industries: metallurgy, medical and pharmaceutical, light industry and many others. Further, sodium sulfite used in the photographic and photo kinodela.
Anhydrous sodium sulfite (sodium sulfite) was obtained by crystallization concentrated sulphite solutions or by dehydration of crystalline sodium sulfite.
Chemical formula: Na 2 SO 3 . Certificate
Sodium sulfite decomposes on heating and on combustion producing toxic and corrosive sulfur oxides. The substance is a strong reducing agent and reacts with oxidants. The containers can explode when heated. Under the action of acid decomposes with the release of sulfur dioxide SO 2 , which is the degree of influence on the organism of the substances of the 3rd class of danger. Sodium sulfite harmful by inhalation, ingestion, contact with skin and eyes.
