Answer:

if blue vitriol is heated, white is the colour of anhydrous substance formed.

When heated , Blue Vitriol losses the water of Crystallization attached .Also , the colour changes from Blue to White as it becomes Anhydrous

Explanation:

Cupric sulfate, CuSO4, commonly known as blue vitriol, is the most important salt of copper. It usually crystallizes as CuSO4 · 5H2O and has a bright blue colour. It is prepared by the treatment of copper oxides with sulfuric acid.

If blue crystalline CuSO4·5 H2O is heated strongly, the hydration water is driven off, leaving white powdery CuSO4 ("anhydrous" copper(II) sulfate).
