Chapter 16, Problem 16.28P

Interpretation Introduction

Interpretation:

The two half reactions that correspond to the oxidation of iodine ion in equation ${\text{H}}_{\text{3}}{\text{O}}^{+}+{\text{I}}^{-}+{\text{H}}_{\text{2}}{\text{O}}_{\text{2}}\stackrel{\begin{array}{l}\text{thyroid}\text{}\text{peroxide}\\ \text{(enzyme)}\end{array}}{\to }\text{I}-\text{OH}+{\text{2H}}_{\text{2}}\text{O}$ is to be stated.

Concept introduction:

A species gains or loses electrons to form anions or cations respectively. A gain in electron is classified as a reduction reaction and loss of electron is classified as an oxidation reaction. The oxidation and reduction reaction are simultaneously occur in redox reaction.
