11.1 Introduction

Electrolysis is nothing but the process by which electrical energy produce chemical changes. This process can be normally used for the extraction of pure metal from their ores, the refining of metals, the building up of worn parts in metallurgical, chemical, and in other industries.

11.2 Principle of Electrolysis

The basic principle of electrolysis is, whenever a DC electric current is made to pass through the solution of salt, some metals can be separated from them. These separated metals can be coated on any object ...
