Chapter 19, Problem 35A

Interpretation Introduction

Interpretation:

The effects in terms of electrons when an atom is oxidized and reduced is to be explained.

Concept introduction:

Concept involves the study of redox reaction. The reaction in which oxidation and reduction takes place simultaneously is called redox reaction.

Answer to Problem 35A

When an atom is oxidized, it loses its electrons and converts into cation

When an atom is reduced, it accepts some electrons and converts intoanion.

Explanation of Solution

The species which undergo oxidation is said to be oxidized and which undergo reduction is said to be reduced. Oxidation is the loss of electrons and reduction is the gain of electrons.

Thus when an atom is oxidized, its electrons are lost and when an atom is reduced, it accepts some electrons.

Conclusion

When an atom is oxidized, it loses its electrons and converts into cation whereas an atom is reduced, it accepts some electrons and converts into anion.
