what is mean by the water of crystallization? Explain that the crystalline salts contain water of crystallization
Answers
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.
Answer:
water of crystallisation is a fixed number of water molecules present in one formula unit of a salt. one formula unit of copper sulphate contains five water molecules . the water molecules which from part of the structure of a crystal are called crystallization. when hydrated salts are heated strongly, they lose their water of crystallisation
on strong heating , blue copper sulphate crystals turn white (due to the loss of water of crystallization)
CuSO4.5H2O__heat____ CuSo4 + H2O
anhydrous copper sulphate turns blue on adding water.
CuSO4 +5H2O-_____CuSO4.5H2O
