Determining the oxidizer and reducer

Postby ursulavictorino1K » Sun Mar 08, 2020 11:45 pm

Given 2 reactions, how do you distinguish which is the oxidizer and which is the reducer?

The reaction with the more positive Ecell is has a higher oxidizing power, the more negative has a higher reducing power.

The oxidizer gains electrons bc they reduce the other agent, and vice versa.

Oxidizing agent gains electrons while the reducing agent loses electrons. It's kinda like the opposite as usual.

A key concept to understand is that an oxidizing agent is more likely to be reduced while a reducing agent is more likely to be oxidized.

Familiarize yourself with the LEO (loss of electron, oxidization) and GER (gains electrons, reduction) acronyms, they help identify what is being reduced and oxidized. From there you also have to know that the species that is being reduced in the 'oxidizing agent' and the one being oxidized is the 'reducing agent'.

In determining the oxidizing agent and reducing agent, I would suggest figuring out the various oxidation states first.

The oxidizing agent is the one that is reduced and the reducing agent is the one that is oxidized!

In an oxidation half reaction, electrons are found on the product side of the equation and the oxidation number of the species being oxidized (called the reducing agent) increases. In a reduction reaction, electrons are found on the reactant side of the equation and the oxidation number of the species being reduced (called the oxidizing agent) decreases.

the oxidizing agent is the reactant that gets reduced, whereas the reducing agent is the one that gets oxidized

The oxidizer has a higher oxidation number and the reducer has a lower oxidation number.
