8. Describe how crystals of copper sulphate are prepared.
The crystals of copper sulphate are prepared as follows:
1. A cup of water is taken in a beaker.
2. Add some drops of dilute sulphuric acid in it.
3. Heat it and when it starts boiling add copper sulphate powder slowly with continuous stirring.
4.The copper sulphate powder is added till saturation level.
5. Filter the solution and cool it.
6. Leave it undisturbed and we will observe copper sulphate crystals after some hours.
Crystals of copper sulphate are prepared :-
1) Take a beaker and put few glasses of water and then put copper sulphate on it and mix them put and mix hence, the solution is not make saturated solution.
2) Then heat the beaker for few minutes and cold for only 1 minute and then put rope in it and leave it few time when check them the crystals of copper sulphate are paste on it .
