Oxidized vs oxidizing agent

Postby Hannah Krusenoski 2L » Fri Feb 16, 2018 12:32 am

How do you differentiate between when something is oxidized or reduced and when it is called an oxidizing agent or reducing agent?

An oxidizing agent removes electrons from something that's being oxidized and is thus reducing itself, while a reducing agent gives electrons to the thing being reduced and oxidizes itself. The book gives examples for the oxidizing agent (O2, O3, MnO4-, and Fe3+) and the reducing agent (H2, H2S, and SO32-).

You can tell when something is being oxidized when you see that an atom, ion, or molecule loses an electron, or in the oxidation half-reaction when an element's oxidation number increases. Similarly, you can tell when something is being reduced when an atom, ion, or molecule gains an electron. In the reduction half-reaction, you can see that the oxidation number of an element has decreased.

Usually, the molecule/atom that has been reduced (gains electrons) is the oxidizing agent and the molecules that has been oxidized (loses electrons) is the reducing agent. This makes sense since redox-reactions involve an exchange of electrons between different atoms/compounds.

The species that is oxidized is the reduction agent, the one that is reduced is the oxidizing agent. This is because if something oxidizes another thing, it must be itself reduced, vice versa.

Oxidizing agents oxidize the species that it is reacting with, and reducing agents reduce the species it is reacting with

Oxidizing agents are reduced--they accept the electron from the molecule that is oxidized. Reducing agents are oxidized--they donate an electron to the molecule that is reduced.
