Synthesis of copper sulfate by electrolysis

I explain how I make copper sulfate crystals from copper metal via electrolysis. The procedure demonstrates the electrochemical reaction between copper metal and sulfuric acid forming copper sulfate. I demonstrate the difference in appearance of anhydrous copper sulfate and copper sulfate pentahydrate.
Copper sulfate can be used in a number of applications including electroplating, preparing Benedict’s solution, use as an antifungal agent, and even in medical applications.
In a follow up video I utilize the crystals to build an inexpensive and very useful medical device. I’ll provide a link to that video here when it’s complete.
