Question
Chapter 4, Problem 5Q
Interpretation Introduction
Interpretation:
The circumstances suitable for the use of a mixture of solvents to carry out recrystallization 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
