i really need to know where they sell copper sulfate in maryland for my school project so it would be great help if u could tell me.
Copper sulfate is used as a fungicide and a fertilizer. Your should be able to get some in lawn and garden stores or ranch/farm stores. Just look at the ingredents. This stuff is not pure, but you can dissolve in in water, filter and then recrystallize to make in more pure.
