Question
Chapter 4, Problem 4Q
Interpretation Introduction
Interpretation:
The reason for the use of smaller quantity of activated charcoal instead of its larger quantity should be determined.
Concept introduction:
Recrystallization is a technique that is used to purify the impure compounds. It is based on the principle that the solubility of substances increases with the increase in temperature.
Following are some of the types of recrystallization:
- Single-solvent recrystallization
- Multi-solvent recrystallization
- Hot filtration-recrystallization
