Crystallization of Copper Sulfate | Class 10 Chemistry Practical | PDW
In this video, Sir explains PBA Experiment 08 in which pure blue crystals of copper(II) sulfate pentahydrate (CuSO₄·5H₂O) are prepared by the process of crystallization. This experiment is very important for Class 10 Chemistry Practical Examination and Practical Based Assessment (PBA).

What you will learn in this lecture:
• Definition of crystallization
• Preparation of hot saturated solution
• Hot filtration method
• Formation of pure blue crystals
• Precautions for better crystal growth
• Observation & conclusion
• Viva questions for PBA
Theory (Exam Oriented):
Crystallization is used to purify soluble solids. When a hot saturated solution is cooled slowly, the solubility decreases and pure crystals separate out, while impurities remain in the mother liquor.
Important for:
Class 10 practical
Board viva preparation
Federal Board chemistry students
PBA full marks preparation
Class 10 PBA Experiment 08 – Preparation of pure CuSO₄·5H₂O crystals by crystallization. Complete practical, viva & precautions explained.
