Copper sulfate is usually encountered as a blue liquid solution, or in blue crystalline form, and is often used in chemistry classes because it is relatively simple to make, and it can be used to demonstrate many interesting reactions, and grow beautiful blue crystals. Copper sulfate also has many practical uses in agriculture, pool maintenance, and the arts and can be readily purchased at many online retailers for these applications.<ref name="rf1">http://www.copper.org/resources/properties/compounds/table_a.html</ref> You can make copper sulfate at home or in the classroom in a number of ways. Just remember that copper sulfate is a skin irritant that is toxic if ingested. Use caution and appropriate safety gear when handling chemicals, and dispose of them carefully after your experiment. | Copper sulfate is usually encountered as a blue liquid solution, or in blue crystalline form, and is often used in chemistry classes because it is relatively simple to make, and it can be used to demonstrate many interesting reactions, and grow beautiful blue crystals.

#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. | #Evaporate the solution to recover the crystals.

#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. | #Dispose of excess copper sulfate solution correctly.
