Sodium Disulfite 0.52 %

Sodium disulfite / sodium metabisulfite 0.52% serves as a laboratory chemical with numerous applications in various scientific fields. One of its main uses is in the food industry as a preservative, stabilizer or antioxidant. In chemical analysis, this solution is particularly suitable for redox and titration experiments, as it has both antioxidant and reductive properties.

The physical and chemical properties of this solution depend on the concentration of sodium disulfite and the reactions that occur. Sodium disulfite (Na2S2O5) is readily soluble in water and decomposes into sodium hydrogen sulfite (NaHSO3) and sodium sulfite (Na2SO3) upon contact with water. Because it acts as a reducing agent in these processes, it is an important helper in the removal and reduction of oxidizing agents.

Possible results of using this chemical compound depend, of course, greatly on the particular experiment or procedure used. In analytics, this solution is often used for the determination of chloride, sulfate, or bromide concentrations. Its use in the food industry can, for example, stabilize vitamin C contents or influence the fermentation of beverages.
