The solid dissolves with more SO2 to give the disulfite, which crystallizes as it cools down. Sodium sulfite (sodium sulphite) is the inorganic compound with the chemical formula Na 2 SO 3. It decomposes when heated. The anhydrous form is much more stable against oxidation by air. a) Burning sodium in chlorine b) The chemical formation of iron(II) sulfide from its elements ... Na2SO3 … [1], Sodium sulfite can be prepared by treating a solution of sodium hydroxide with sulfur dioxide. The two oxygen atoms, being much more electronegative than the metals take these four electrons and thus have an oxidation state of $-2$ each. See the answer. For a number of drugs, they are often used as a preservative to help improve shelf life. The oxygen (3.5) is more electronegative than sulfur (2.5), thus the oxygen would have an oxidation number of -2. Emits toxic fumes of sodium oxide and oxides of sulfur if heated to decomposition [Lewis, 3rd ed., 1993, p. 1174]. The sodium atom has a radius of 185.8 pm and a Van der Waals radius of 227 pm.
