Salt metabisulfite is a chemical compound with the formula Na2S2O5. It is additionally called salt pyrosulfite as well as sodium disulfite. Na2S2O5 is an ionic compound including the salt cation (Na+) and also the metabisulfite anion (S2O52-). In its common state, salt metabisulfite exists as a white or yellowish-white powder. This compound has a faintly pungent odor equivalent to that of sulfur dioxide. It is important to remember that salt metabisulfite may create allergies in humans that are sensitive to sulfites.
Framework of a Sodium Metabisulfite Molecule
The disulfite (or metabisulfite) anion includes a straight connection between both sulfur molecules. The first sulfur particle is bound to three oxygen atoms and also shows an oxidation state of +5 whereas the various other sulfur atom reveals an oxidation state of +3 and is abided by two oxygen atoms.
When the solution of NaHSO3 (sodium bisulfite) is filled with SO2 (sulfur dioxide) and afterwards allowed to vaporize, a deposit of sodium metabisulfite is gotten. The equilibrium feedback can be written as adhered to.
2HSO3– ⇌ S2O52- + WATER
