Heya

Here's your answer

Aim: To show copper sulphate crystal contain water of crystallization.

Procedure

● Take few crystal of copper sulphate in a dry boiling tube.

● Heat the test tube over the burner.

Observation: the blue-coloured crystal trun white and some water droplets are seen deposited over the cooler part of the boiling tube.

Conclusion: this show that blue-coloured crystal of hydrated copper sulphate trun white due to loss of water of crystallization.

Remove the boiling tube away from the flame and allow it to cool. now add few drops of water and you will observe that anhydrous copper sulphate (white) turns blue. this is due to formation of hydrated copper sulphate again.

CuSO₄(s) + 5H₂O(l) → CuSO₄•5H₂O

glad help you
it helps you,
thank you

Heya, buddy!

AIM - To determine the water of crystallization.

Materials we need - copper sulphate crystals, test tube holder, burner, boiling tube.

Procedure - ★ heat few crystals of copper sulphate in a dry boiling tube.

★we will observe that on heating blue crystals of copper sulphate, it becomes colourless and few drops of water are seen on the test tube.

★ then, on adding few drops of water to the heated copper sulphate, the blue colour of copper sulphate reappears.

the water of crystallisation is the fixed number of water molecules present in one formula unit of salt.

glad to help uh! ^_^
