How Do You Seperate, Copper Sulphate, Water And Sand?
I like the first answer up until the very end. When you evaporate off the water completely and turn it to a gas, you are left with a white powder that is anhydrous copper II sulfate. As long as the powder is blue, it is still holding water in it as hydrated copper II sulfate. There can’t be such a thing as anhydrous copper sulfate solution, since anhydrous means no water, and solution means water…. It is interesting that the blue copper II sulfate hydrate compound actually changes color as you heat it and drive off the water to become anhydrous copper II sulfate.
