Chapter 20, Problem 54A

Interpretation Introduction

Interpretation:

The diagram representing the electrolytic cell and the half cell reactions needs to be drawn. The maximum voltage or standard potential of battery needs to be determined.

Concept introduction:

A chemical cell converts chemical energy to electrical energy. It usually consists of two separate half cells which provide the flow of electrons due to difference in cell potentials.

Answer to Problem 54A

Reaction at tin half cell:

$Sn\to S{n}^{2+}+2e^{-}$

Reaction at copper half cell:

$C{u}^{2+}+2e^{-}\to Cu$

Maximum voltage of this battery is 0.48V.

Explanation of Solution

Oxidation potential of half cell=0.14V

Reduction potential of half cell=0.34V

Potential difference of cell=0.14+0.34=0.48V

Conclusion

The diagram for the cell can be drawn in the above manner and the maximum potential of the cell is 0.48V
