Chapter 17, Problem 6RQ

Interpretation Introduction

Interpretation:

The condition for common ion effect in concentration cell is given. The concept of concentration cell along with effect of common ion effect in the concentration cell is to be stated.

Concept introduction:

The difference in ion concentration in different compartments leads to the formation of the concentration cell.

The common ion effect also affects the value of the cell potential.

To determine: The definition of concentration cell; the value of $E{°}_{\text{cell}}$ in the concentration cell; driving force for a concentration cell to produce a voltage; concentration of ion at anode; effect of decreased concentration of ion at anode and/or increased concentration of ion at cathode over cell potentials; effect of addition of $\text{NaCl}$ to the anode compartment (refer Fig.17-9); the value of $\left[{\text{Ag}}^{+}\right]$ at anode using the given $E_{\text{cell}}$.
