  2. Sodium bisulfite - Wikipedia

    en.wikipedia.org/wiki/Sodium_bisulfite

    SO 2 + NaOH → NaHSO 3 SO 2 + NaHCO 3 → NaHSO 3 + CO 2. Attempts to crystallize the product yield sodium metabisulfite (also called sodium disulfite), Na 2 S 2 O 5. [6] Upon dissolution of the metabisulfite in water, bisulfite is regenerated: Na 2 S 2 O 5 + H 2 O2 Na + + 2 HSO 3 −. Sodium bisulfite is formed during the Wellman-Lord ...

    en.wikipedia.org/wiki/Sodium_sulfite

    When conducted in warm water, Na 2 SO 3 initially precipitates as a white solid. With more SO 2, the solid dissolves to give the disulfite, which crystallizes upon cooling. [2] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O. Sodium sulfite is made industrially by treating sulfur dioxide with a solution of sodium carbonate. [3] The overall reaction is:

    When conducted in warm water, Na 2 SO 3 initially precipitates as a yellow solid. With more SO 2, the solid dissolves to give the disulfite, which crystallises upon cooling. [4] SO 2 + 2 NaOH → Na 2 SO 3 + H 2 O SO 2 + Na 2 SO 3 → Na 2 S 2 O 5. which yields a residue of colourless solid Na 2 S 2 O 5.

  5. Sulfur dioxide - Wikipedia

    SO 2 + 2 H 2 S → 3 S + 2 H 2 O. The sequential oxidation of sulfur dioxide followed by its hydration is used in the production of sulfuric acid. SO 2 + H 2 O + 1 ⁄ 2 O 2 → H 2 SO 4. Sulfur dioxide dissolves in water to give "sulfurous acid", which cannot be isolated and is instead an acidic solution of bisulfite, and possibly sulfite, ions.

    2 O 2− 5), also known as disulfite: 2 HSO − 3 ⇌ S 2 O 2− 5 + H 2 O. Because of this equilibrium, anhydrous sodium and potassium salts of bisulfite cannot be obtained. However, there are some reports of anhydrous bisulfites with large counter ions. [4] Structure of disulfite (aka metabisulfite) ion. [5]

    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).
