Chapter 8, Problem 8I.13E

Interpretation Introduction

Interpretation:

The oxidation of ${\text{Mn}}^{\text{2+}}$ to permanganate ion in an acidic solution by chlorine gas has to be determined.

Concept Introduction:

Electrode potential:

The potential related to each electrode refers to electrode potential.  If the species concentration participating in the electrode reaction is unity and the reaction occurs at $\text{298K}$ then the potential of the electrode refers to as Standard Electrode Potential ${\text{(E}}^{\text{0}}\text{)}\text{.}$ The electrode reaction is at unity when any gas participating in the particular electrode reaction is approximately 1 atmospheric pressure.

The formula for electrode potential is,

  ${\text{E}}^{\text{o}}{}_{\left(\text{cell}\right)}{\text{=E}}^{\text{o}}{}_{\left({}_{\text{reduction}}\right)}{\text{-E}}^{\text{o}}{}_{\left(\text{oxidation}\right)}$

If ${\text{E}}^{\text{o}}{}_{\left(\text{cell}\right)}\text{<}\text{0}$ then the reaction is not possible.

If ${\text{E}}^{\text{o}}{}_{\left(\text{cell}\right)}\text{>}\text{0}$ then the reaction is possible.
