Determining the oxidizer and reducer

[ursulavictorino1K]

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

[Eesha Chattopadhyay 2K]

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.

[Brandon Valafar]

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.

[ValerieChavarin 4F]

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.

[Kallista McCarty 1C]

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

[William Francis 2E]

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.

[Nikki Razal 1L]

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

[Joanne Lee 1J]

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