Chapter 5, Problem 5I.2ST

Interpretation Introduction

Interpretation:

The formation of water $\left({\text{H}}_{\text{2}}\text{O}\right)$ from hydrogen $\left({\text{H}}_{\text{2}}\right)$ and oxygen $\left({\text{O}}_{\text{2}}\right)$ has to be expressed in two half reduction reactions.

Concept Introduction:

Redox reaction:

  In this type of reactions, both oxidation and reduction takes place.  One of the species gets oxidized while the other species gets reduced.

$\begin{array}{l}oxidation:\text{losing}\text{of}\text{an}\text{electron}\text{by}\text{a}\text{species}\\ reduction:\text{gaining}\text{of}\text{an}\text{electron}\text{by}\text{a}\text{species}\end{array}$
