One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
