Copper Sulphate (CuSO4) Copper Sulphate pentahydrate (CuSO 4 5H 2 O) is commonly known as Blue Vitriol. It is obtained in lab by dissolving CuO, Cu (OH) 2 or CuCO 3 in dil H 2 SO 4. The solution on crystallization gives blue triclinic crystals of CuSO 4 5H 2 O. In large scale, CuSO 4 is obtained by reacting scrap copper with hot and dilute H 2 ...

o Feed concentration: Cu MW = 63.54, so 12 g sulfate/L is (CuSO 4. 5H 2 O MW = 249.6) is close to 3 g Cu/L. o The feed solutions should be made up by the TA. o If weakly acidic copper sulfate in water is used as feed, less copper will be extracted from the aqueous phase. Thus the equilibrium will depend on the pH of the aqueous phase.
