Question

Identify the species oxidized, the species reduced, the oxidizing agent and the reducing agent in the following electron transfer reaction.

2Fe3+ + Sn2Fe2+ + Sn2+
species oxidized species reduced



oxidizing agent reducing agent





As the reaction proceeds, electrons are transferred from
to
.

Answer 1

Here are the definitions.
Loss of electrons is oxidation.
Gain of electrons is reduction.
The material oxidized is the reducing agent.
The material reduced is the oxidizing agent.

2Fe3+ + Sn ==> 2Fe2+ + Sn2+

You can see that 2Fe^3+ goes from 6+ to 4+ so that is a gain of electrons.

You can see Sn goes from 0 on the left to 2+ on the right which is a loss of electrons
