Question

17. Identify the following reactions as either oxidation
reduction :
(i) O + 2e → 02- ​

Answer 1

Answer:

Answer

Oxidation is the loss of electrons or an increase in the oxidation state of an atom, an ion, or of certain atoms in a molecule.

Reduction is the gain of electrons or a decrease in the oxidation state of an atom, an ion, or of certain atoms in a molecule

in this given reaction (O+2e

−

→O

−2

), there is the gain of electrons thus, this is reduction reaction.
