Q. How to syntesize copper (II) sulfate pentahydrate in a lab, starting from copper?
Asked by Dejan S - Mon Apr 7 07:52:14 2008 - - 3 Answers - 0 Comments
A. With Concentrated acid the reaction of copper Metal with Sulphuric acid will be Cu + 2H2SO4 --> CuSO4 + SO2 + 2H2O Copper + Sulphuric Acid --> Copper Sulphate + Sulphur Dioxide + Water With Dilute acid the reaction of copper Metal with Sulphuric acid will be Cu + H2SO4 --> CuSO4+ H2 Copper + Sulphuric Acid --> Copper Sulphate + Hydrogen using some excess of metal and removing it after reaction by simple filtration, the resulting blue solution can be evaporated to super saturation and allowed CuSO4 to crystal out and separate. These crystals should be filtered and dried in a desiccator (instead of under heat) to ensure that the water of crystallisation is not lost.
