Potassium sulfite, K2SO3·2H2O; potassium hydrogen sulfite, KHSO3; white solids, similar in properties and formation to the corresponding sodium sulfites. | [Chemical Properties]
White crystals or powder. Soluble in

| [Definition]
potassium sulphite: A white crystallinesolid, K2SO3, soluble in waterand very sparingly soluble inethanol; r.d. 1.51; decomposes onheating. It is a reducing agent and isused as such in photography and inthe food and brewing industries,where it prevents oxidation. | [Synthesis]
Similar to other alkali metal sulfites, potassium sulfite can be produced by passing sulfur dioxide through a solution of potassium hydroxide, and if the sulfur dioxide is in excess, potassium bisulfite is obtained. Zinc powder or sodium amalgam can reduc |
