硫化钠是一个无机盐类，化学式为Na2S，通常以九水合物Na2S·9H2O的形式存在。无水物和九水物都是无色可溶的固体，在水溶液中水解呈强碱性。露置在空气中时，硫化钠会放出有臭鸡蛋气味的有毒硫化氢气体。

Sodium sulfide 硫化钠
Sodium sulfide is the chemical compound with the formula Na2S, or more commonly its hydrate Na2S·9H2O. Both are colorless water-soluble salts that give strongly alkaline solutions. When exposed to moist air, Na2S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Some commercial samples are specified as Na2S·xH2O, where a weight percentage of Na2S is specified. Commonly available grades have around 60% Na2S by weight, which means that x is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as 'sodium sulfide flakes'. Although the solid is yellow, solutions of it are colorless.
