Chapter 19, Problem 19.75SP

Interpretation Introduction

Interpretation:

The given chemical species, $A{l}_{(s)},P{b}_{(s)}{\text{ and Fe}}_{(s)}$ are to be arranged in order of increasing strength under standard state conditions.

Introduction:

The half-cell potential of a reduction reaction is called the standard reduction potential. Whenever the direction of the half-reaction is reversed, the sign of the half-cell potential also reverses. This means, if the half-cell potential was positive, it becomes negative if the direction of the reaction is reversed. According to these half-cell potential values, we can determine the oxidizing or reducing strengths of different chemical species via comparison.
