I wanted to separate Basic Copper Sulphate(WSDTY) from water. My compound is also soluble in water. I've tried with filtration and other method like reverse phase column chromatography, But still I didn't find any solution for that. Firstly we have to heat the CuSO4 solution to a saturated solution (about 3/4 of the water has vaporised). Then leave the solution in a beaker to cool it. When the solution is let to cool down, crystallization will occur. Normally we left it to form the crystals for 3 days. When you cool it, be sure to cover the solution so that no impurities will go inside. After that, filter the crystal out. Then put it on a dry filter paper and let it dry. The salt formed is blue in colour which is not a copper sulphate salt. It is still hydrated (CuSO4.5H2O). To form the salt which is white in colour, you need to heat the hydrated CuSO4.5H2O salt strongly. CuSO4.5H2O --> CuSO4 + 5H2O
For fast crystallization, you can create some inter-phase by seeding with small crystal of copper sulfate or put a glass rod inside the solution. As mentioned by Rafik Karaman, the crystals obtained will be hydrated copper sulfate, so you have to heat it to obtain anhydrous copper sulfate.
