Understand the preparation of Hydrogen Sulphide. Click on the link to Watch the VIDEO explanation: Watch Video
The apparatus is arranged in the Video. A few pieces of iron Sulphide are taken in the round bottom flask. Dilute HCl acid is poured into it until the lower part of thistle funnel is covered by the acid. Reaction takes place and hydrogen sulphide gas evolved. This gas is collected in the gas jar through upward displacement of air.
