describe an experiment to prepare a pure, dry sample of a soluble salt,
starting from an insoluble reactant ( prepare a sample of pure, dry hydrated copper (II) sulfate crystals starting from copper (II) oxide )
- add excess insoluble base to the acid
- filter to remove unreacted base
- heat the solution so that water evaporates and crystals of the salt remain
copper oxide (base) is insoluble
