if a substance causes another substance to be oxidized, that substance is a(n) agent. likewise, the substance that is oxidized i
Inessa [10]

If a substance causes another substance to be oxidized, that substance is an oxidizing agent. Likewise, the substance that is oxidized in an electrochemical reaction is always the reducing agent.

An Oxidizing agent is the one that gets reduced by accepting electrons. It causes oxidation because it makes the other substance lose electrons.

Oxidizing agents also transfer one electronegative atom like oxygen to the other chemical substance. Halogens are an example of oxidizing agents.

A reducing agent is the one that gets oxidized because it loses electrons in a redox reaction. It loses electrons and achieve a higher oxidation state. Lithium is an example of a reducing agent.
