Explain the following reaction with their balanced chemical equation.
Hydrogen sulphide reacts with sulphur dioxide.
Solution
Hydrogen sulphide and sulphur dioxide react to form sulphur and water. It is a redox reaction.
\[\ce{\underset{\text{Sulphur dioxide}}{SO_{2(g)}} + \underset{\text{Hydrogen sulphide}}{H2S_{(g)}} -> \underset{\text{Sulphur}}{S_{(s)}} + \underset{\text{Water}}{H2O_{(l)}}}\]
