Potassium sulfite (formula: K2SO3) is an inorganic compound. It is a white odorless granular powder at room temperature, soluble in water, and its aqueous solution is weakly alkaline. Slightly soluble in ethanol. In addition to anhydrous substances, potassium sulfite can also form monohydrate and dihydrate. It is primarily used as a food preservative, with the E code E225. 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).
