Understand the definitions of oxidation and reduction: Oxidation is the loss of electrons, and reduction is the gain of electrons.
Recognize that in any redox reaction, oxidation and reduction always occur simultaneously but in different species; one species loses electrons (oxidized) and another gains electrons (reduced).
Note that redox reactions are not limited to aqueous solutions; they can occur in gases, solids, and other phases as well.
Identify that the statement 'Reduction is the process of losing electrons' is incorrect because reduction involves gaining electrons, not losing them.
Conclude that the true statement is: 'Oxidation involves the loss of electrons, while reduction involves the gain of electrons.'
