Question

explain oxidation and reduction in terms of loss or gain of electrons​

Answer 1

Answer:

oxidation is addition of oxygen and it gains electrons

reduction is addition of h2 and it loses electrons

Explanation:

Answer 2

Oxidation is the process in which loss of electrons take place.

Reduction is the process in which gain of electrons take place.

There are cases in which both oxidation and reduction take place. Such a chemical reaction is known as REDOX reaction.

Let us take an example:

$\bold{Cu {}^{2 + } + Mg - - - > Cu + Mg {}^{2 + } }$

Here, Cu^2+ is oxidized to Cu and Mg is reduced to Mg^2+
