Chapter 15, Problem 15.DE

a)

Interpretation Introduction

Interpretation:

The potential with response with ion-selective electrode, if the electrode were immersed in $\text{5}\text{.00}\text{mM}\text{NaCl}$ at pH $\text{ 8}\text{.00}$ has to be calculated.

Concept Introduction:-

Response of ion-selective electrode:

The response of an ion-selective electrode to its primary ion (A) and to interfering ions of the same charge, when the response to every ion is Nernstian.

$\text{E=}\text{constant+}\frac{\text{0}\text{.05916}}{{\text{z}}_{\text{A}}}\text{log}\left[{\text{A}}_{\text{A}}\text{+}{\displaystyle \sum _{\text{X}}^{}{\text{K}}_{\text{A,X}}^{\text{Pot}}}{\text{A}}_{\text{X}}\right]$

b)

Interpretation Introduction

Interpretation:

The potential with response with ion-selective electrode, if the electrode were immersed in $\text{1}\text{.00}\text{mM}\text{NaCl}$ at pH $\text{3}\text{.87}$ has to be calculated.

Concept Introduction:-

Response of ion-selective electrode:

The response of an ion-selective electrode to its primary ion (A) and to interfering ions of the same charge, when the response to every ion is Nernstian.

$\text{E=}\text{constant+}\frac{\text{0}\text{.05916}}{{\text{z}}_{\text{A}}}\text{log}\left[{\text{A}}_{\text{A}}\text{+}{\displaystyle \sum _{\text{X}}^{}{\text{K}}_{\text{A,X}}^{\text{Pot}}}{\text{A}}_{\text{X}}\right]$
