what happens when copper sulphate solution is heated?
Answer Wiki. Copper sulfate is generally a blue color. It is sometimes called blue copper for this reason. When the copper sulfate is heated up, it quickly turns to a pure white color that has no hint of blue in it. Water also comes out of the copper sulfate and is able to function as any other type of water would typically function.When the copper sulfate becomes hot, it begins to become dehydrated.
