It readily oxidized when heated, producing sodium carbonate and sulphur dioxide. In the production of rubber chemicals, sulfur dyes and other chemical compounds are used. Charles C. Price, Gardner W. Stacy "p-Aminophenyldisulfide" Org. The WellmanLord process utilizes sodium sulfite for flue gas desulfurization, Sodium sulfite is primarily used as a mild reducing agent. National Ocean Service, Chemical PAC-1 PAC-2 PAC-3; Sodium sulfide (1313-82-2) 0.62 mg/m3 : 6.9 mg/m3 : 41 mg/m3 Used in matches, gunpowder and medicines, sulfur along with many other elements, is used to create a number of ions, or charged molecules. Despite the fact that the solid-state is yellow, the solution is colourless. Web site owner: Sodium sulfide is strongly alkaline. Another factor that contributes to sodium sulfides water solubility is that it is an ionic molecule that tends to dissociate its ions in water. Ions that are oppositely charged become attracted to one another and form an ionic bond.
