Chapter 5, Problem 5.64P

(a)

Interpretation Introduction

Interpretation:

Standard potential of the cell for the given cell should be determined.

Concept introduction:

Cell potential can be calculated from the electrode potentials as follows,

$E_{cell}^0=E_{right}^0-E_{left}^0$

(b)

Interpretation Introduction

Interpretation:

Cell potential of the given cell should be determined where the molar concentration of $H{g}^{2+}\text{ = 0}\text{.230 mol}{\text{.dm}}^{-3}$ and the molar concentration of $T{l}^{+}\text{ = 0}\text{.720 mol}{\text{.dm}}^{-3}$.

Concept introduction:

Cell potential can be calculated from the electrode potentials as follows,

$E_{cell}^0=E_{right}^0-E_{left}^0$

Cell potential of a cell can be determined using Nernst equation as follows,

  $E_{cell}{\text{ = E}}_{cell}^o-\frac{RT}{\nu F}\ln Q\boxed{\begin{array}{c}\text{F = Faraday's constant}\\ \nu \text{ = No}\text{. of electrons transferred}\\ {\text{E}}_{cell}^o\text{ = Standard cell potential}\end{array}}$
