WebIn the presence of water droplets, in the form of fog, clouds, rain or hygroscopic aerosols, sulfur dioxide dissolves, so that aqueous-phase oxidation can give rise to bisulfite and sulfite. These equilibria are sensitive to pH, and HSO 3-is the predominant species over the pH range of 2–7. 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…
