galena lead sulfide

Sulfide

This mineral form of lead sulfide is called galena. The term sulfide (sulphide in British English) refers to several types of chemical compounds containing sulfur in its lowest oxidation number of −2.. Formally, sulfide is the dianion, S 2−, which exists in strongly alkaline aqueous solutions formed from H 2 S or alkali metal salts such as Li 2 S, Na 2 S, and K 2 S. Sulfide is Get price
