What will happen when the crystals of blue vitriol are heated?

Answer»

Blue vitriol, as we know it, is hydrated Copper(II) Sulphate, meaning CuSO4.5H2O. ... When blue vitriol is HEATED, those WATER of CRYSTALLIZATION escape out of the crystal and what's LEFT is anhydrous copper sulphate or simply CuSO4, without any water of crystallization.
