Interpretation Introduction

Interpretation:

The potential would vary if the electrode were immersed in ${\text{10}}^{\text{-5}}\text{M}\text{NaF}$ and the pH ranged from $\text{1}\text{to}\text{13}$ 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.

Ion-selective electrode obeys following equation.

$\text{E=constant-0}\text{.05916log}\left[{\text{CN}}^{\text{-}}\right]$
