Bisulfit oxidation
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO3. Sodium bisulfite in fact is not a real compound, but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions. It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide. For properties of sodiu… WebJan 1, 1993 · A comparison between the outcome of these calculations and the experimental results shows that the sulfite oxidation mechanism depends on the bisulfite concentration. Furthermore, it is argued that uncatalyzed sulfite oxidation is to be recommended as a model reaction for mass transfer studies as an alternative to cobalt …
