Chapter 19, Problem 100IAE

Interpretation Introduction

Interpretation:

It should be shown that $E^0=\frac{{\displaystyle \sum n_i{E}_i^0}}{{\displaystyle \sum n_i}}$ and the standard reduction potential for ${\text{H}}_6{\text{IO}}_6{\text{(aq) + 5 H}}^{+}{\text{(aq) + 2 I}}^{-}\text{ (aq) + 3e }\to \frac{1}{2}{\text{ I}}_2{\text{(s) + 4 H}}_2\text{O(l) + 2 HIO(aq)}$ should be calculated.

Concept introduction:

Standard reduction potential is tendency of a chemical species to be reduced at standard conditions.

Gibbs free energy of a half cell reaction is given by the following equation:

$\Delta G^0=-nF{E}^0$

Here,

$\Delta G^0$ - Standard Gibbs free energy

n − Number of electrons

F − Faraday constant

$E^0$ - Standard reduction potential of the half cell
