Concept Introduction: The chemical reaction in which oxidation and reduction take place simultaneously is known as
a)
Answer to Problem 15SP
The nitrogen atom of
Explanation of Solution
Oxidation is the removal of an electron and the species that undergo oxidation and reduce another species is known as the reducing agent. Similarly, the reduction is the addition of an electron or oxygen atom, and the species that undergo reduction by oxidizing other species is known as a reducing agent.
The given reaction,
The reaction can also be written as,
The oxidation number of Nitrogen is calculated as follows:
So, let the oxidation number of the nitrogen atom of
So, let the oxidation number of the nitrogen atom of
The oxidation number of nitrogen in
is calculated as follows:
Let the oxidation number of the nitrogen atom of
In water molecules, the charge of the hydrogen atom is
Thus, from the reaction, it is concluded that the Nitrogen atom of
