Concept explainers
(a)
Interpretation
For the given pairs - reducing agent and gain of electrons, whether the concepts of pairing are correct or not have to be indicated.
Concept Introduction:
Reducing agent:
The substance which is getting oxidized in
Example:
Consider the reaction:
Oxidation No of
Oxidation No of
Oxidation No of Nitrogen in
Oxidation No of Hydrogen in
Hence
(b)
Interpretation:
For the given pairs – substance oxidized and increases in oxidation number, whether the concepts of pairing are correct or not has to be indicated.
Concept Introduction:
Oxidation:
Loss of electrons from an atom ion or molecule during a
Example
Here
Oxidizing agent:
Oxidizing agent will gain electrons but itself will get reduced in the reaction. Oxygen, Hydrogen peroxide are good oxidizing agent.
Example:
Consider the reaction:
Oxidation No of
Oxidation No of
Oxidation No of Nitrogen in
Oxidation No of Hydrogen in
(c)
Interpretation
For the given pairs – oxidizing agent and gain of electrons, whether the concepts of pairing are correct or not have to be indicated.
Concept Introduction:
Oxidation:
Loss of electrons from an atom ion or molecule during a chemical reaction is known as oxidation. Oxidation state of atom ion or molecule will increase in this process. In simple it is the addition of oxygen. Reduction is gaining of electrons.
