In the past few decades, however, interest in hydrates has soared, especially in petroleum-poor countries like Japan. Heating a hydrate drives off the water molecules, and the solid that is left behind is called anhydrous (which means without water). The idea is reminiscent of a perpetual motion machine, says Kvenvolden. In many cases, the uptake and loss of water (by heating, decreasing pressure, or other means) are reversible processes, sometimes accompanied by changes in colour. These solids are known as deliquescent substances. Use: In its hydrate form, copper sulfate turns a vivid blue color and has been used as a coloring ingredient in paintings and pottery. When you overheat the hydrate, you drive off all the water, but lose some of the anhydrous CuSO4 , which breaks down to form copper (II) oxide. are all hydrates colored compounds?
