Question

an ore on reacting with dilute acid gives a gas which has a smell of rotten eggs. identify the ore and write its steps of metallurgy

Answer 1

the gas is H2S and the ore is a sulphide ore

Answer 2

H2S or the hydrogen sulphide is one of the most bad smell generating gases which smells like rotten eggs or vegetables.

We can easily prepare the H2S or the hydrogen sulphide gas in the laboratory.

By using any sulphide metal ore and the diluted H2SO4 or the sulphuric acid.

This process is the most easy process to produce H2S or the hydrogen sulphide gas in the laboratory.
