S.R. Clough, in Encyclopedia of Toxicology (Third Edition), Abstract. Sodium sulfite (CAS ) is an odorless, solid white powder with a salty sulfurous taste that is soluble in water. It is primarily used as a food preservative (e.g., to prevent dried fruit from discoloring) and as an antioxidant. Overview. Sodium sulfite (SO-dee-um SUL-fite) is a white powder or crystalline solid with no odor but a slightly salty taste. The compound is stable in dry air, but tends to decompose in moist air to produce sulfur dioxide (SO 2) and sodium hydroxide (NaOH).The compound has a variety of uses as a food preservative and in the paper and pulp industry. Sodium Sulfite, Anhydrous Safety Data Sheet according to Federal Register / Vol. 77, No. 58 / Monday, Ma / Rules and Regulations Issue date: 08/02/ Revision date: 11/06/ Supersedes: 04/11/ Version: 11/06/ EN (English US) Page 1 SECTION 1: Identification. Identification. Product form: SubstanceFile Size: KB. Preparation. Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur conducted in warm water, Na 2 SO 3 initially precipitates as a yellow solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling.. SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O. Sodium sulfite is made industrially by treating sulfur dioxide with a.

Sodium sulfite (sodium sulphite) is a soluble compound of sodium. Its chemical formula is Na2SO3. It has a molecular weight of It is a product of SO2 scrubbing, a part of the flue gas desulfurization process. Sodium sulfite by reacting sodium carbonate solution with sulfur dioxide. Sodium sulfite (Na 2 SO 3) is a white, water-soluble, crystalline solid with a sulfurous, salty decomposes when heated. It is generally available f in powder, crystalline, and tablet forms. Sodium sulfite is yet another dechlorinating agent widely used by utilities. In this process, sulfomethylation was conducted with (w/w) sodium hydroxymethyl sulfonate/lignin for 2 h at °C under alkaline conditions. 98 Sodium hydroxymethyl sulfonate was used instead of sodium sulfite. 28 The product was determined to have a lower sulfur content of wt % and higher molecular weight of 11 g mol −1 than.

The consumption of sodium sulfite and production facilities in each region is also changing with respect to the pulp & paper industry whereas Brazil is the dominant country. China is the leading producer of sodium sulfite across the globe. (b) Sodium sulfite heptahydrate is a transparent or white crystalline solid with not more than a faint odour of sulfur dioxide. Biological Data The biological data as they were available at the end of have been summarized in the document entitled "Specifications for Identity and Purity and Toxicological Evaluation of Some Antimicrobials. The following pie chart shows world consumption of sodium sulfate in Mainland China is the world’s largest market and is growing at about 1–2% annually. It has the largest reserves of mirabilite (a major source of natural sodium sulfate) and has been building and .
