How is calcium sulfide ( CAS ) converted to carbon?
CaS is produced by “carbothermic reduction” of calcium sulfate, which entails the conversion of carbon, usually as charcoal, to carbon dioxide :
Which is the active ingredient in calcium sulfide?
The active ingredient is probably a calcium polysulfide, not CaS. Calcium sulfide decomposes upon contact with water, including moist air, giving a mixture of Ca (SH) 2, Ca (OH) 2, and Ca (SH) (OH). It reacts with acids such as hydrochloric acid to release toxic hydrogen sulfide gas.
