In the given reaction, Cu will be oxidized and N will be reduced.

Removal of electrons or just a rise in an element's oxidation state are both considered to be oxidation.

Gaining electrons or lowering the oxidation state of an element or its constituent atoms are both examples of reduction.

The given reaction is : Cu + HNO3 → Cu(NO3)2 + NO + H2O.

In the reactant side , the oxidation number on Cu = 0

In the product side , the oxidation number on Cu = +2

Then , it is known as the increasing the oxidation number is considered as oxidation process.

In the reactant side , the oxidation number on N = +5

In the product side , the oxidation number on N = +2

Then , it is known as the decreasing the oxidation number is considered as reduction process.

Therefore, in the given reaction, Cu will be oxidized and N will be reduced.

To know more about oxidation and reduction.
