Calcium sulfide (CaS), a donor of hydrogen sulfide (H(2)S ...

Calcium sulfide (CaS), one of the effective components in a traditional herb, is another donor of H(2)S. It has more stable chemical properties than NaHS. We hypotheses that CaS might be given by mouth as a new antihypertensive drug through certain dosage form designing. To test this hypothesis, we should establish animal models for studies ...

Calcium Sulfide - an overview | ScienceDirect Topics

Hydrogen sulfide is produced by the action of acids on sulfide minerals. For example, the reaction of galena with an acid to produce hydrogen sulfide can be represented as. (16.4)PbS + 2 H+ → Pb2+ + H2S. The reaction of calcium sulfide with H2 O and CO 2 also produces sulfur. (16.5)CaS + CO2 + H2O → H2 + S + CaCO3.
