Chapter 17, Problem 148CP

(a)

Interpretation Introduction

Interpretation:

A concentration cell having Copper electrodes at different concentration is given. The cell potential for the given concentration cell at the given concentration of ions and the value of new cell potential after enough ${\text{NH}}_3$ is added to the left compartment at equilibrium condition is to be calculated.

Concept introduction:

A cell consisting of electrodes of same type which have different concentration of ions is called concentration cell. The difference in ion concentration in different compartments is the driving force for the formation of the concentration cell.

To determine: The potential for the given concentration cell.

The value of cell potential for the given cell is $\underset{\_}{0.118V}$.

To determine: The value of new cell potential after enough ${\text{NH}}_3$ is added to the left compartment at equilibrium condition.

The value of new cell potential for the given cell is $\underset{\_}{0.38V}$.
