Interpretation:
The species that undergo oxidation has to be identified.
Concept introduction: Those reactions in which one species undergoes reduction and other oxidation simultaneously are known as
Oxidation is defined as loss of electrons or increase in the oxidation state of a molecule, ion or atom. The species which loses electrons or whose oxidation state is being increased is said to be oxidized and is called reducing agent.
Reduction is defined as a gain of electrons or decrease in the oxidation state of a molecule, ion or atom. The species which gain electrons or whose oxidation state is being reduced is said to be reduced and is called oxidizing agent.
(b)
Interpretation:
The species that undergoes reduction has to be identified.
Concept introduction: Those reactions in which one species undergoes reduction and other oxidation simultaneously are known as redox reactions.
