Chapter 23: Q. 23.1 (page 631)

What is meant by the Nernstian behavior of an indicator electrode?

Short Answer

Expert verified

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

Step by step solution

01

Given information

State the Nernstian behavior of an indicator electrode.

02

Nernst equation for a reaction 

An indicator electrode is a type of electrode that is used in potentiometric titrations. It is used as an endpoint indicator. Membrane electrodes 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 involved in the reaction.
