Solutions

Chapter 23, Problem 23.1QAP
Interpretation Introduction

Interpretation:

The nernstian behavior of an indicator electrode should be predicted.

Concept introduction:

Potentiometric titration are the simple titration that is used to measure the concentration of the given sample. No indicator is required in these titrations.

Expert Solution

Answer to Problem 23.1QAP

The nernstian behavior of an indicator electrode states that an electrode follows the Nernt equation and its potential is changed by 0.059/nV.

Explanation of Solution

Indicator electrode is a type of electrode that is used in potentiometric titrations. It is used as an endpoint indicator. Membrane electrode and metallic electrodes are classified as indicator electrodes. The nernstian behavior corresponds to the Nernst equation. If the indicator electrode shows the nernstian behavior, it means that it follows the Nernst equation. In other words, the potential of the indicator electrode would be changed by 0.059/nV with respect to the change in concentration, where n is the number of electrons involve in the reaction.

Conclusion

When the indicator electrode represents the nernstian behavior that means it follows the Nernst equation and its potential is changed by 0.059/nV.
