#Evaporate the solution to recover the crystals.  You can evaporate the solution by pouring it into a shallow glass dish that is exposed to the air for several days. You can also speed the process up by boiling the solution carefully in a heat-resistant (pyrex or borosilicate) pan, and then pouring off the last bit of sulfuric acid that does not evaporate.  Be careful, as the solution in question is caustic and should be handled with great care.

#Dispose of excess copper sulfate solution correctly. Copper sulfate is toxic to fish, plants, and other wildlife and should not be poured into lakes or streams, or rinsed down the storm drain. Copper sulfate is a common ingredient in many drain cleaners, and small quantities, like what this experiment will yield, can be safely diluted with water and rinsed down the sink.
