Chapter 18, Problem 18.38QE

Interpretation Introduction

Interpretation:

The reason for not considering the given balanced reaction as a proper redox reaction has to be given.

  ${\text{ O}}_{\text{2}}\text{(g)}\text{+}\text{2}{\text{H}}_{\text{2}}\text{O}{\text{(l)+ I}}_{\text{2}}\text{(s)}\to \text{ 4}{\text{OH}}^{\text{-}}\text{(aq)+}\text{2}{\text{I}}^{\text{-}}\text{(aq)}$

Concept Introduction:

Redox reaction: It occurs when oxidation and reduction takes place at the same time in a chemical reaction.

Oxidation: If electrons are moved from a species during a chemical reaction. The species whose electrons are removed is said to be oxidized.

Reduction: If electrons are gained to a species during a chemical reaction. The species which gets electrons are said to be reduced.
