Chapter 18, Problem 82E

Interpretation Introduction

Interpretation:

The likelihood of HClO₂ to undergo disproportionation reaction needs to be predicted based on the given half reactions.

Concept Introduction:

Redox reactions are chemical reactions that are expressed in terms of reduction and oxidation half reactions. They involve transfer of electrons between two species.

Oxidation reaction involves loss of electrons whereas reduction is accompanied by the gain of electrons.

The standard voltage (E°) for the cell is the sum of the standard voltages of the reduction and oxidation half reactions i.e.

  $\begin{array}{l}{\text{E}}^{\text{0}}{\text{ = E}}_{\text{red}}^{\text{0}}{\text{- E}}_{\text{oxd}}^{\text{0}}\\ {\text{(or) E}}^{\text{0}}{\text{ = E}}_{\text{cathode}}^{\text{0}}{\text{- E}}_{\text{anode}}^{\text{0}}\text{ ----------(1)}\end{array}$
