To determine which element is being oxidized, this is one approach that can be used.

Note: oxidation numbers are very similar to ionic charges, or charges that form as metals and nonmetals, undergo chemical bonding.

1) To note down the oxidation numbers for all elements/atoms in the substances, and then observe that if it is increasing then it is being oxidized, if it is reducing then it would be being reduced.

Zn + CuSO4 -> ZnSO4 + Cu

O +2 -2 -> +2 -2 0

Ignore the -2 as these are spectator ions that do not undergo the change, and are not part of the main reaction occurring.

Here we can see that Zn goes from 0 to +2, thus it would be oxidized, while Cu goes from +2 to 0, thus is reduced.

An element is said to be oxidized when they chemically react with an oxygen atom. In the reaction between zinc and copper sulfate, the zinc element is said to be oxidized.

What is oxidation?

In a redox reaction the atoms and molecules losses and gains electron to change their oxidation state by completely transferring their electrons to another atom in the reaction mixture.

Oxidation is the process of redox where the atom losses its electron which can be said as an increase in its oxidation number by giving away its electron or by the addition of oxygen.

The balanced reaction is given as,

Zn + CuSO₄ → ZnSO₄ + Cu

Here, the oxidation number of zinc changes from 0 to +2, and of copper from +2 to 0. It can be inferred that zinc got oxidized, while copper got reduced.

Therefore, in the reaction zinc got oxidized.
