Question

Identify from the following which is not an oxidizing agent.
(A) Oxygen
(B) Aluminum
(C) Chlorine
(D) Sulphuric acid

Answer 1

Hint: To answer this question, we first need to understand what agents are agents. A chemical agent is a substance that has a hazardous effect on human health. Dusts, mixes, and even ordinary materials like paints, fuels, and solvents are included in this classification. Chemical agents are employed for a variety of purposes, from crowd control to chemical warfare.

Complete answer:
Oxidizing agent – Oxidizing agent, also known as an oxidizing agent, is a chemical that has the ability to oxidize other compounds by accepting their electrons. Oxygen, hydrogen peroxide, and halogens are common oxidizing agents.
In one definition, an oxidizing agent is a chemical entity that obtains one or more electrons through a chemical process. In that respect, it's a part of a redox (oxidation–reduction) reaction. An oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate in the second sense. Atom-transfer reactions are involved in combustion, numerous explosives, and organic redox reactions.
So, we conclude that, Because of its low standard reduction potential, aluminum (Al) works as a reducing agent. Furthermore, because aluminum is at the top of the reactivity scale, it has the power to reduce or replace all other metals with lower reactivity.
So, the final answer is option (B) i.e., Aluminum.

Note:
Redox is a chemical reaction that involves changing the oxidation states of atoms. Redox reactions are defined as the actual or formal movement of electrons between chemical entities, with one species often experiencing oxidation while the other experiences reduction.
