Chapter 19, Problem 42E

Interpretation Introduction

Interpretation:

Whether the displacement of Pb(s) from 1.0 M $\text{Pb}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ can be carried out by tin metal or not should be explained.

Concept introduction:

In an electrochemical cell, there are two electrodes that can be observed.

If oxidation takes place on an electrode, that electrode is called anode. The species in that electrode remove electrons and itself gets oxidized.

If reduction takes place on an electrode, that electrode is called cathode. The species in that electrode absorbs electrons and itself gets reduced.

The one with highest reduction potential tends to reduce first.
