1.

Name the substance oxidised and reduced, and also identify the oxidising agents and reducing agents in the following reactions : H_(2)S+SO_(2)toS+H_(2)O

Answer»

Solution :`2H_(2)S+SO_(2)to3S+2H_(2)O`
`H_(2)S` has lost H to change into S. Thus, it has been oxidised. `SO_(2)` has lost O to change into S. Thus, it has been reduced. `H_(2)S` has ACTED as REDUCING agent while `SO_(2)` has acted as oxidising agent.
