Question

What is meant by Water of crystallization of
a substance Describe an activity to show
that the Copper Sulphate Crystals Contain
water of crystallisation​

Answer 1

Answer:

Water of crystallization is the fixed number of water molecules present in one formula unit of a salt.

When we heat copper sulphate in china dish, the blue coloured crystals changes into a white powder due to the removal of 5 molecules of water of crystallization.so, it is proved that copper sulphate contains water of crytalisation...

Hope it us helpful

plz mark in brainliest!!

Answer 2

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.
