Chapter U5.17, Problem 1TAI

Interpretation Introduction

Interpretation: The transfer of electrons in oxidation reaction needs to be explained.

Concept Introduction: Oxidation of metal is exothermic. So, oxidation reactions are a potential source of energy for our daily lives. To explore the usefulness of metal oxidation as an energy source, we must examine and compare the amount of thermal energy transferred during these reactions.

Answer to Problem 1TAI

In oxidation reaction, an atom or ion loses electrons.

Explanation of Solution

Whenever an atom or ion loses electrons, another atom gains electrons. Loss of electrons is known as oxidation, and gain of electrons is known as reduction. Oxidation and reduction always occur together. This process is known as oxidation-reduction, or redox. When metals react with oxygen to form metal oxides, the metal atoms are oxidized and the oxygen is reduced. To extract elemental metals, the reverse reaction must occur and metal ores must be reduced.

Conclusion

Oxidation indicates the process of losing electrons.
