Question

How do you prepare hydrogen sulfide?

Answer 1

Hint: As we know that hydrogen sulfide is a chemical compound. It’s IUPAC name is Hydrogen sulphide. The chemical formula is ${H_2}S$. Hydrogen sulphide is colourless, highly corrosive, flammable and poisonous with the repellent odour of rotten eggs. The key use of this gas is in the manufacturing sector. We will understand how to prepare hydrogen sulphide in description.

Complete answer:
Here we have to find how to prepare hydrogen sulphide.
When we mix one part of sulphur and two parts of paraffin wax and they are heated above ${160^ \circ }C$. Hydrogen sulphide is formed during the reaction. The rate of reaction is proportional to temperature.
This reaction is fast and accurate. We have to keep in mind that the reaction mixture must not be heated above ${200^ \circ }C$, since a lot of paraffin vapour clogs the tubes.
Hence we can write the chemical reaction stating the above: ${C_x}{H_y} + S\xrightarrow{{}}{H_2}S + {C_x}{H_z}$.

Note:
We should note that hydrogen sulphide is typically evolved from iron sulphide, that is broken into small lumps and then treated with dilute hydrochloric acid or sulphuric acid. The iron sulphide gas is produced by the reaction of dilute hydrochloric acid or sulphuric acid. The molar mass of hydrogen sulphide is $34.08g.mo{l^{ - 1}}$.
