Question

The gas with the smell of rotten eggs

Answer 1

• On passing hydrogen through boiling sulfur, we obtain hydrogen sulfide (H₂S) gas.

. ${\mathrm{H}}_2\left(\mathrm{g}\right)+\mathrm{S}\left(\mathrm{s}\right)\to \underset{\mathrm{Hydrogen}\mathrm{sulfide}}{{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)}$

• Hydrogen sulfide has the smell of rotten eggs.
• This gas is used in analytical work.
• It is a colorless, flammable gas
