Chapter 18.2, Problem 1RQ

Interpretation Introduction

Interpretation: The oxidizing and reducing agent in an oxidation-reduction reaction needs to be explained.

Concept Introduction: In oxidation-reduction reaction, transfer of electron/s takes place. The transfer of electron, results in the formation of ions. In oxidation, loss of electron/s takes place and in reduction, gain of electron/s takes place.

Answer to Problem 1RQ

In oxidation-reduction reaction, oxidizing agent is electron acceptor while reducing agents is an electron donor.

Explanation of Solution

Oxidizing agents gain one or more electrons from another reactant. Oxidizing agent is reduced because it accepts electrons. A reactant which gives electrons to another reactant is termed as reducing agent. A reducing agent is oxidized because it donates one or more electrons.

Conclusion

Oxidation is caused by losing electrons and reduction is caused by gaining electrons.
