Details:

Application: Potassium sulfite (formula: K2SO3) is an inorganic compound. It is a white, odorless, granular powder at room temperature. It is mainly used as a food preservative.

Preparation: Similar to other alkali metal sulfites, potassium sulfite can be prepared by passing sulfur dioxide into a potassium hydroxide solution, and if sulfur dioxide is excessive, potassium bisulfite is obtained. Zinc powder or sodium amalgam can reduce potassium sulfite to potassium dithionite (K2S2O4).

Identification test: Potassium test (IT-27) and sulfite test (IT-30) of 5% sample solution were positive. Soluble in water, insoluble in ethanol (OT-42).

Content analysis: The sample was accurately weighed about 750mg and dissolved in the mixed solution composed of 100.0 ml of 0.1mol/L iodine and 5ml of dilute hydrochloric acid test solution (TS-117). The excess iodine was titrated with 0.1mol/L sodium thiosulfate, and the starch test solution (TS-235) was added as an indicator. 0.1mol/L of iodine per milliliter is equivalent to potassium sulfite (K2SO3)7.912mg.

Use 1. Preservative; Antioxidants; Bleach; Anti-browning agent. 2. Antioxidants. The developer. 3. For analytical purposes. 4. Used as a general reagent, but also used in the photographic industry.
