How: To make cupric sulfate you would need 10 mL of 30% hydrogen peroxide, and 3 mL of concentrated (98%) sulfuric acid along with a piece of copper. Mix the hydrogen peroxide and concentrated sulfuric acid in a beaker and put in the piece of copper. Once you have done that you can sit back and watch the reaction that is being made. Once that is done they put it in a container with a label and sell it.
