Chapter 17, Problem 22AE

Interpretation Introduction

Interpretation:

Among $\text{K}$, $\text{Ca}$, $\text{Mg}$, $\text{Al}$, $\text{Zn}$, $\text{Fe}$, $\text{H}$, $\text{Cu}$ and $\text{Ag}$ most easily oxidized element and least easily oxidized element has to be determined.

Concept Introduction:

The series in that metals are arranged in order of increase in electrode potential is termed as electrochemical series. The arrangement of metals as per their reduction potential is as follows:

  $\text{K}>\text{Ca}>\text{Mg}>\text{Al}>\text{Zn}>\text{Fe}>\text{H}>\text{Cu}>\text{Ag}$

Oxidation process represents loss of electrons. Reduction process represents gain of electrons.
