Chapter 15, Problem 15.31P

a)

Interpretation Introduction

Interpretation:

The principle of operation of an ion-selective electrode has to be explained.

Concept introduction:

Ion-selective electrode

An ion-selective electrode (ISE) best known as a specific ion electrode (SIE), is a sensor (or transducer) that transforms the activity of a specific ion dissolved in a solution into an electrical potential.

b)

Interpretation Introduction

Interpretation:

The difference between compound electrodes from an ion-selective method has to be explained.

Concept introduction:

Compound electrode: The chemical active membrane outside the ion-selective membrane is known as compound electrode.

Ion-selective electrode

An ion-selective electrode (ISE) best known as a specific ion electrode (SIE), is a sensor (or transducer) that transforms the activity of a specific ion dissolved in a solution into an electrical potential.
