sodium sulfide
Properties:
The method solution in the air will slowly oxidized to glucosinolate and sodium, sodium sulfite, or sodium and more show. Because of glucosinolate and sodium generating speed faster, so the oxidation of major product is glucosinolate and sodium. The method in the air, constantly release hydrogen sulfide gas. Industrial method for containing impurities its colour and lustre are pink and palm red and yellow. Specific gravity, melting point, boiling point, but also because of impurities influence and different.
Use:
Analytics reagents used as cadmium, such as metal ions of precipitation agent. Also used in photographing, mineral flotation, metal processing, zinc and cadmium electroplating.
