Chapter 20, Problem 43A

Interpretation Introduction

Interpretation:

The anode of zinc carbon dry cells is to be explained. The reaction which takes place at anode is to be explained.

Concept introduction:

Anode is that electrode where oxidation is occurs.

Answer to Problem 43A

The zinc sleeve is behaves as an anode.

The oxidation process is occurring at anode or zinc sleeve. So, the oxidation process at anode is given as

$\text{Zn}\to {\text{Zn}}^{\text{+2}}{\text{+2e}}^{\text{-}}$

Explanation of Solution

The zinc electrode is behaves as an anode because the electrons flow from the zinc sleeve to the carbon rod in a zinc carbon dry cell.

The oxidation process is occurring at anode or zinc sleeve. So, the oxidation process at anode is given as

$\text{Zn}\to {\text{Zn}}^{\text{+2}}{\text{+2e}}^{\text{-}}$

The metal container will be made up of zinc whose base is made up of negative electrode or anode and a carbon rod act as a cathode or positive electrode. It surrounding by manganese dioxide low moisture electrolyte.

Conclusion

The zinc sleeve is behaves as an anode.

The oxidation process is occurring at anode or zinc sleeve. So, the oxidation process at anode is given as

$\text{Zn}\to {\text{Zn}}^{\text{+2}}{\text{+2e}}^{\text{-}}$
