Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO 3. Sodium bisulfite is not a real compound, [ 2 ] but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions.
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 ...
The bisulfite ion (IUPAC-recommended nomenclature: hydrogensulfite) is the ion HSO − 3. Salts containing the HSO − 3 ion are also known as "sulfite lyes". [1] Sodium bisulfite is used interchangeably with sodium metabisulfite (Na 2 S 2 O 5). Sodium metabisulfite dissolves in water to give a solution of Na + HSO − 3. Na 2 S 2 O 5 + H 2 O ...
Sulfites or sulphites are compounds that contain the sulfite ion (systematic name: sulfate(IV) ion), SO 2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, [1] its salts are widely used. Sulfites are substances that naturally occur in some foods and the human body.
Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4. Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).
The oxidation state of the sulfur atom bonded to 3 oxygen atoms is +5 while oxidation number of other sulfur atom is +3. [3] The anion consists of an SO 2 group linked to an SO 3 group, with the negative charge more localized on the SO 3 end. The S–S bond length is 2.22 Å, and the "thionate" and "thionite" S–O distances are 1.46 and 1.50 ...
Sodium metabisulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. [3] When 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 crystallises upon cooling. [4] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O SO 2 + Na 2 SO 3 → Na 2 S ...
Hydroxysultaine is prepared industrially by the reaction of sodium bisulfite with epichlorohydrin to give the sodium salt (sodium 1-chloro-2-hydroxypropane sulfonate). [1] This is similar to the synthesis of isethionate , which is also used as a 'head-group' in surfactants.
