WebConclusion. In conclusion, the empirical formula of hydrated copper sulphate can be determined as CuSO4· 5H2O by experiment. Water molecules can make the copper complex ion blue. Ammonia (NH3) causes deep blue colour, and chloride ions (Cl-) make the copper complex solution yellow-green. Therefore, the nature of ligands can affect … Web16 nov. 2024 · As a result of the loss of water during crystallisation, blue copper sulphate crystals turn white when heated vigorously. Copper sulphate crystal dehydration is a reversible process. As a result, adding water to anhydrous copper sulphate causes it to become hydrated and turn blue, resulting in the production of hydrated copper sulphate. eggs price in pick n pay
