उत्तर
When pieces of blue vitriol are heated in a test tube, then the crystal structure of blue vitriol breaks down to form a colourless powder and water comes out. This water is called water of crystallization. when water is added to the same test tube, the white powder turns into a blue colour again. This is due to reversible reactions taking place from anhydrous salt to hydrous salt and vice-versa.
