Chapter 23, Problem 102A

Interpretation Introduction

Interpretation:

Voltaic cell needs to be defined.

Concept introduction:

A device having capacity to generate energy (electrical) from chemical reaction or use electrical energy to result chemical reactions is known as cell. Electrochemical cells are of two kinds, galvanic (Voltaic) and electrolytic cell.

Answer to Problem 102A

From chemical reactions electrical energy is produced in voltaic cell.

Explanation of Solution

An electrochemical cell that produces electricity from chemical reactions is termed as voltaic cell. In an electrochemical cell, two half cells are present which are connected by a salt bridge. In each cell there is an electrode present. Current flows between these two electrodes. One electrode is known as cathode and another is known as anode.

Conclusion

In electrolytic cell, electrical energy is used to result chemical reactions.
