| | POTASSIUM SULFITE Usage And Synthesis |
| Chemical Properties | White crystals or powder. Soluble in
water; sparingly soluble in alcohol; decomposes on
heating and slowly oxidizes in air. | | Chemical Properties | Potassium sulfite, K2SO3·2H2O; potassium hydrogen sulfite, KHSO3; white solids, similar in properties and formation to the corresponding sodium sulfites. | | Uses | Potassium Sulfite is used as a fabric treatment chemical. | | Uses | Photographic developer, medicine (cathartic),
food and wine preservative. | | 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. | | Safety Profile | When heated to
decomposition it emits toxic fumes of SOx
and K2O. See also SULFUROUS ACID and
SULFITES. | | 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 reduce potassium sulfite to potassium conidiosulfite (K2S2O4). |
