description The chemical compound sodium sulphide has the formula Na2S. It is a crystalline, soluble in water solid that quickly collects moisture from the atmosphere due to its hygroscopic nature. When sodium sulfide interacts with acids, hydrogen sulfide gas is released, giving sodium sulfide its characteristic strong smell, which is similar to rotten eggs. Sodium sulfide anhydrous (Na2S) and sodium sulfide nonahydrate (Na2S·9H2O) are the two forms that are most often seen.
