is known to be a colorless and pungent-smelling gas.
It can be detected by using a Potassium permanganate solution.
When is made to pass through an acidified Potassium permanganate solution having a pink-violate color, it decolorizes the solution as it reduces ions to ions giving out a suffocating smell that indicates its presence.
The balanced chemical reaction for the above reaction can be given as;
Therefore, in the above way, we can detect the presence of the gas gas.
