Sodium sulfide is a chemical compound with the formula Na2S. They are colourless and when dissolved in water give a strongly alkaline solution. When exposed to moist air, sodium sulfide and its hydrates emit strong hydrogen sulfides that smells like rotten eggs. Industrially, sodium sulfide is produced by the carbothermic reaction of sodium sulfate using coal. In this short piece of article, let us learn more about the sodium sulfate formula and its chemical structure along with the various uses of sodium sulfide.
