Chapter 21, Problem 21.2P

Interpretation Introduction

Interpretation:

The reason that why should electrochemical process involves redox reaction has to be identified.

Concept Introduction:

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.

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

Electrochemistry: It deals with the study of relationship between chemical change and electrical work.
