Hydrogen Sulphide (H2S) — Chemistry Keypoint

Hydrogen Sulphide (H2S)

by

Hydrogen Sulphide is found in volcanic gases and goal gases during the decaying of sulphur riched organic compound.

Laboratory Preparation of Hydrogen Sulphide

It is prepared laboratorily by the action of dilute acid on metallic sulphide.
FeS(s) + 2HCL(aq)   →  FeCL2(aq) + H2S(g)

NB: Kipp’s apparatus is used in the production of H2S and also CO2.
