Question

In a chemical reaction, oxidation is always accompanied by reduction.
If true enter 1, else enter 0.

• A. 1

Answer 1

The correct option is A 1
In a chemical reaction, oxidation is always accompanied by reduction.
One species is oxidized and the other species is reduced. The electrons released by one species are accepted by other species.
For example, in the reaction: $C{u}^{2+}+Zn\rightleftharpoons Cu+Z{n}^{2+}$, Zn is oxidized to $Z{n}^{2+}$ and $C{u}^{2+}$ is reduced to Cu.
