    en.wikipedia.org/wiki/Sodium_bisulfite

    Sodium bisulfite is an example of an antichlor. Historically, sodium bisulfite has been used in the textile industry, cosmetic industry, food industry, and more. [3] [4] Antichlors are very useful in the textile industry because bleaching of compounds using chlorine is a standard practice.

    en.wikipedia.org/wiki/Bisulfite

    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 ...

    Sodium sulfite used industrial as a corrosion inhibitor/oxygen scavenger. Monoprotonation of sulfite gives HSO 3 −, which is called bisulfite. The sodium and potassium salts of bisulfite are not available, but solid and solutions of the approximate formula NaHSO 3 and KHSO 3 are widely marketed as sodium bisulfite and potassium bisulfite.

    en.wikipedia.org/wiki/Sodium_bisulfate

    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 use of sodium bisulfite as a blocking agent has also allowed them to be used in waterborne resins such as PUDs. [19] Similarly, vanillin maybe used as an isocyanate blocker and is actively being researched. It is then used in single component waterborne coatings. [20]

    en.wikipedia.org/wiki/Sulfite_process

    These chemicals cleave the bonds between the cellulose and lignin components of the lignocellulose. A variety of sulfite/bisulfite salts are used, including sodium (Na +), calcium (Ca 2+), potassium (K +), magnesium (Mg 2+), and ammonium (NH 4 +). The lignin is converted to lignosulfonates, which are soluble and can be separated from the ...
