Answer 1

Answer:

The process of deriving large crystals of pure substances from their solutions is known as crystallisation. It is a physical change. Crystals of salt are obtained by the evaporation of sea water. ... This mixture when filtered and allowed to cool produces crystals of copper sulphate.The process of deriving large crystals of pure substances from their solutions is known as crystallisation.
