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.
The city was disposing of sodium bisulfite that had been stored since 2019 at the Franzen Reservoir’s Chlorine Reduction Facility in Turner. Sodium bisulfite is generally used to remove excess ...
After secondary treatment, 85% of the pollutants in the waste stream have been removed. The stream is then treated with sodium hypochlorite to kill bacteria, and then with sodium bisulfite to remove the chlorine. The waste stream is then discharged into a 9.5-mile long, 24-foot diameter gravity-powered outfall tunnel that bores underneath the ...
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 ...
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.
