Chapter U5.112, Problem 1TAI

Interpretation Introduction

Interpretation:The use of redox reaction as an energy source needs to be explained.

Concept introduction: In an electrochemical cell, the energy is expressed in voltage. The overall voltage is measured as the difference between the potentials of the half cells.

Answer to Problem 1TAI

The transfer of electrons that occur during oxidation-reduction can be converted into electrical energy.

Explanation of Solution

The transfer of electrons that occur during oxidation-reduction can be converted into electrical energy. The electrical energy can be stored and controlled by separating the reactants into half-cells. The activity series helps to choose electrodes and electrolytes that will produce the electricity. The voltage can be calculated from the half-cell potentials of an electrochemical cell.

Conclusion

A redox reaction be used as an energy source in an electrochemical cell.
