What is hydrated copper sulphate? - Quora
WebHydrated copper sulphate CuSO4 ⋅5H2 O is blue in colour. The ligand (water) molecules causes splitting of d orbitals. This facilitates d-d transition and colour. Anhydrous copper sulphate CuSO4 is colourless. In the absence of ligand (water) molecules, splitting of d orbitals is not possible. Hence, d-d transition is not possible. WebCuSO4•5H2O is the blue copper sulfate pentahydrate. Adding iron filings: CuSO4•5H2O + Fe = FeSO4 + 5H2O (l) + Cu Change in Free Energy: ΔG (20C) = -129.9kJ (negative, so the reaction runs) Change in Enthalpy: ΔH (20C) = -79.4kJ (negative, so the reaction is exothermic) The colour of FeSO4 is light green.
