SODIUM METABISULPHITE

[CODE NO.4365]  

Sodium metabisulfite or sodium pyrosulfite (IUPAC spelling; Br. E. sodium metabisulphite or sodium pyrosulphite) is an inorganic compound of chemical formula Na2S2O5. 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, Na2SO3 initially precipitates as a yellow solid. With more SO2, the solid dissolves to give the disulfite, which crystallises upon cooling.

SO2 + 2 NaOH ? Na2SO3 + H2O

SO2 + Na2SO3 ? Na2S2O5

Which yields a residue of colourless solid Na2S2O5

Sodium pyrosulphite is sometimes considered to be a solid for of sulphur dioxide since it contains 67% SO2. The principal use of sodium pyrosulphite is as a reducing agent and as a preservative for various food stuffs. In these applications it is being used as a convenient solid replacement for sulphur di­oxide.

A potential use of both sulphur dioxide and sodium pyrosulphite that has high growth possibilities for Western Canada is as a preservative for silage. In the case of grain silage (oats and barley) sulphur dioxide reduces the degree of fermentation (and hence of loss of potential food energy) that lead to acids giving natural preser­vation and, in the case of grass silage that is low in fermentable carbohydrates, the sulphur dioxide provides a reliable method of preservation that may bedifficult to achieve naturally.
