. Reduction can be defined as a gain of electrons or as a decrease in oxidation state. Explain why the two definitions mean the same thing, and give an example to support your explanation.
Interpretation:
The reason should be identified for the same meaning of given two definition of reduction and explain with example.
Reduction can be defined as the gain of electrons or as a decrease in oxidation state.
Concept Introduction:
The chemical reaction in which both oxidation and reduction process takes place is known as redox reaction. In this reaction, transfer of electrons takes place among the elements.
Reduction is the process in which either gain of electrons, oxidation number decreases, or gain of hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
The given two definitions are:
Reduction can be defined as the gain of electrons or as a decrease in oxidation state.
We know that, electrons are negative in charge, when an atom gains electrons, it gains one negative charge for each electrons gained. Thus, decrease in oxidation number takes place.
Hence, when the oxidation state or number of an atom or an element decreases, implies gain of electrons takes place...
