Question

Define water of crystallization. Explain with the halp of an activity that copper sulphate crystall contain water of cystallisation

Answer 1

Water of crystallisation is the number of water molecules that combine chemically in definite molecular proportion, with the concerned salt in the crystalline state. This water is responsible for the geometric shape and colour of the crystals.

For example: the CuSO4.5H2O

_______________________________

✔The process of crystallization is used to purify a solid from its impurities.

✔First of all, we take about 5 gram of impure sample of copper sulphate in a China dish.

✔After that, we dissolve it in minimum amount of water then filter the impurities.

✔Saturate the solution by heating that is when some solid starts evaporating.

✔Then we cover the solution with filter paper and leave it undisturbed to cool slowly for a day.

✔Hence, by this process we will obtain the crystals of copper sulphate in a China dish.
