Natri Sulfua is the name for the chemical compound Na2S, but is usually for sodium salt Na2S · 9H2O. Both salts are colorless and soluble in water to produce a basic solution. When exposed to humid air, Na2S and its salt salts both release hydrogen sulfide that smells like rotten eggs or flat medium. In general, the trade name of sodium sulfide does not exist solely, but it is clearly stated as Na2S · xH2O, in which the content of Na2S is also determined. The common type contains about 60% Na2S in mass, ie x is approximately equal to 3. The type used in the technique has a yellow appearance.
