Question

Oxidation and reduction always occur
simultaneously, hence, the word "redox” was
coined for this class of chemical reactions. In the
following redox reaction, identify the species
undergoing oxidation and reduction:
3Fe3O4 (s) + 8 Al (s) — 9 Fe (s) + 4AlO3 (s)​

Answer 1

Answer:

al - oxidation

fe - reduction

so it is redox reaction

Answer 2

Oxidation and reduction always occur simultaneously, hence, the word "redox” was coined for this class of chemical reactions.

• Oxidation is the deficiency of electrons during a reaction by a particle, atom or ion.
• Oxidation happens when the oxidation condition of a atom, ion or molecule is expanded.
• The contrary interaction is called reduction, which happens when there is an increase of electrons or the oxidation condition of a molecule, atom, or ion diminishes.

In the following redox reaction -

3Fe3O4 (s) + 8 Al (s) — 9 Fe (s) + 4AlO3 (s)​

Al is oxidized as there is addition of oxygen.

On the other hand, Fe is reduced.
