Identify the oxidant and reductant in the following reaction:
`Zn(s)+1/2O_2(g) toZnO(s)`

Text Solution

Verified by Experts

In reaction (a), `Zn` donates electrons to `O` to give zinc and oxide ions. Therefore, `Zn` acts as a reducing agent while oxygen acts as an oxidising agent.
In reaction (b), `Zn` transfers its electrons to `H^(o+)`, and therefore, zinc acts as a reducing agent and `H^(o+)` acts as an oxidising agent.
