Hydrogen sulfide (H2S) is a chemical compound. The gas is colourless, highly corrosive, flammable and poisonous, with the repellant odour of rotten eggs. The key use of gas in the manufacturing sector. Emergency physicians need to be aware of hydrogen sulphide management because quick diagnosis and care are essential to recovery.
Preparation of hydrogen sulfide
One part of sulphur and two parts of paraffin wax are mixed & heated above 160° C. Hydrogen sulphide is formed during the reaction. The rate of reaction is proportional to temperature. The reaction is fast and accurate. The reaction mixture must not be heated above 200 ° C, since a lot of paraffin vapour clogs the tubes.
CxHy + S → H2S + CxHz
- Hydrogen sulphide is typically evolved from iron sulphide, that is broken into small lumps and then treated with dilute hydrochloric acid or sulfuric acid.
- The iron sulphide is put in Kipp’s apparatus and the hydrogen sulphide gas is produced by the reaction of dilute hydrochloric acid or sulfuric acid.
