Question

The process of oxidation involves:
A. The addition of oxygen atoms
B. The acceptance of electrons
C. The release of electrons
D. Neither acceptance nor release of electrons

Answer 1

Oxidation is an important process in chemical reactions. There are many ways to describe an oxidation reaction. When a species undergoes oxidation, its oxidation number changes. Reduction is the opposite process of oxidation.

Complete step by step answer:
In chemistry, there are many definitions for oxidation. They are,
Oxidation is the loss of electrons. When an atom or ion loses one or more electrons we say the species is oxidised.
Oxidation is the increase in oxidation number. When an atom or ion loses one or more electrons its oxidation number increases. Then we say that the species is oxidised.
Oxidation is addition of oxygen. When oxygen atom(s) is/are added to an element, we say that element is oxidised.
Oxidation is removal of hydrogen. When hydrogen atom(s) is/are removed from an element, we say that element is oxidised.
All these definitions are used according to the reaction taking place.

Hence from the given options the correct options are,A,C.

Note: Two terms that confuse people are oxidation and oxidant. Oxidant is the species which oxidises the other species. It gets reduced in the process. Another name for oxidant is oxidising agent. Hence do not get confused between the terms.
