Write the experimental procedure and the observation of removing water of crystallisation from the crystals of copper sulphate
Answers
In this experiment, the water of crystallisation is removed from hydrated copper(II) sulfate. The mass of water is found by weighing before and after heating. This information is used to find x in the formula: CuSO4.xH2O. In this experiment, the water of crystallisation is removed from hydrated copper(II) sulfate.
Explanation:
When salts are heated strongly,they lose their water of crystallisation.By losing water of crystallisation,the hydrated salts lose their regular shape and colour,and become colourless powdery substances,
The salts which have lost their water of crystallisation are called anhydrous salts.
For Ex:Copper sulphate crystals are blue in colour.When copper sulphate crystals are heated strongly,they lose water of crystallisation and form anhydrous copper sulphate which is white in colour.
