Question

The element Sulphur is yellow and has a sharp, offensive odour. When it chemically reacts with hydrogen gas, it forms a new substance called hydrogen sulfide that smells like rotten eggs. Do you think the smell is due to the sulphur in the new substance or is there any other reason? Explain.

Answer 1

The element Sulphur is yellow and has a sharp, offensive odour. When it chemically reacts with hydrogen gas, it forms a new substance called hydrogen sulfide that smells like rotten eggs.Hydrogen sulfide is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage). It is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements, manholes, sewer lines and underground telephone/electrical vaults.the smell is due to the sulphur in the new substance as because just like oxygen and nitrogen hydrogen is both colorless and odorless. It has no smell, i.e. it does not interact with the smell receptors in your nose .
