Concept Introduction: In
Answer to Problem 4RQ
In a reaction, if oxidation state decreases and gaining of electrons takes place then the reaction is termed as reduction.
Explanation of Solution
For an element, decrease in oxidation state results in reduction. As the element takes one or more electrons hence, a decrease in oxidation state occurs. Therefore, reduction is caused by gaining electrons. Below equation is the reduction of chlorine:
In this reaction, oxidation state of Cl decreases from 0 to
In oxidation-reduction reaction, oxidizing agents are electron acceptor while reducing agents are electron donor.
