Structure of anhydrous sodium sulfite. Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na 2 SO 3 initially precipitates as a white solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling. [2] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
The ammonium, sodium, and potassium salts adopt very similar structures in the solid state, according to X-ray crystallography. In the ammonium salt, the O-O distance is 1.497 Å. The sulfate groups are tetrahedral , with three short S-O distances near 1.44 Å and one long S-O bond at 1.64 Å.
It is possible to scrub sulfur dioxide by using a cold solution of sodium sulfite; this forms a sodium hydrogen sulfite solution. By heating this solution it is possible to reverse the reaction to form sulfur dioxide and the sodium sulfite solution. Since the sodium sulfite solution is not consumed, it is called a regenerative treatment.
Lignosulfonates (LS) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. [1] Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. [2]

Sulfite is SO 3 2-, available as its sodium and potassium salts, Na 2 SO 3 and K 2 SO 3, respectively. When dissolved in water, these salts react with oxygen to give the corresponding sulfate salts, which are innocuous. Sodium sulfite used industrial as a corrosion inhibitor/oxygen scavenger. Monoprotonation of sulfite gives HSO 3 −, which is ...
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
