What do you need to know about sodium metabisulfite?
Sodium Metabisulfite 1 Origin. Sodium metabisulfite, also known as sodium pyrosulfite, is an inorganic compound with the chemical formula Na2S2O5. 2 Functions. In cosmetics and personal care products, sodium metabisulfite functions as an antioxidant preservative and a hair-waving/straightening agent. 3 Safety.
What is the chemical structure of anion metabisulfite?
Chemical structure. The anion metabisulfite is a hybrid of dithionite (S 2O 4 2−) and dithionate (S 2O 6 2−). The anion consists of an SO 2 group linked to an SO 3 group, with the negative charge more localized on the SO 3 end.
How is disodium metabisulfite used as a disinfectant?
The substance is sometimes referred to as disodium metabisulfite. It is used as a disinfectant, antioxidant, and preservative agent. Sodium disulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. When conducted in warm water, Na 2 SO 3 initially precipitates as a yellow solid.
How does metabisulfite react with thiolsulfate esters?
The metabisulfite ion (S 2 O 52−) is hydrolysed by water to bisulfite (HSO 3− ), which reacts with protein SS groups by interchange, freeing a SH group on one protein but leaving a thiolsulfate ester on the other protein ( eqs 18.10a and b ).
