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).

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.
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 ...
The Wellman–Lord process is a regenerable process to remove sulfur dioxide from flue gas (flue-gas desulfurization) without creating a throwaway sludge product.. In this process, sulfur dioxide from flue gas is absorbed in a sodium sulfite solution in water forming sodium bisulfite; other components of flue gas are not absorbed.
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.
World Trade Organization members failed to agree on reforms to revive a broken trade dispute settlement system during the last General Council meeting before U.S. President-elect Donald Trump ...
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 ...
