Answer 1

Answer:

Water of crystallization is defined as water that is stoichiometrically bound into a crystal. Crystal salts containing water of crystallization are called hydrates. Water of crystallization is also known as water of hydration or crystallization water.

Answer 2

Water of crystallization is the water molecules that are trapped within the voids of the crystal of compounds and appears in the stoichiometric formula of the compound.

• The two examples of compounds that contains water of crystallization are blue vitriol (CuSO4.5H2O) and green vitriol (FeSO4.7H2O).
• Water of crystallization does make a differnce in the colour of the compounds. for example the blue crystals of hydrated copper sulfate turns white on losing its water of crystallization when the crystals are heated.
