Question
Chapter 21, Problem 21.8QP
Interpretation Introduction
Interpretation:
The main step used in purification of metals has to be described.
Concept introduction:
Purification of metals
The removal of impurities from metals is said to be purification of metals. The classification of purification methods depends on nature of metal and nature of impurities present in it. There are three methods commonly used in the purification of metals.
- Distillation
Electrolysis - Zone refining
