Cobalt chloride paper is absorbent paper which has been soaked in cobalt chloride solution and allowed to dry. It is a convenient way to use cobalt chloride as a test for the presence of water. When cobalt chloride is anhydrous, that is completely without water, it is blue, but when there is water present, either in solution or in the solid, it is pink. To use cobalt chloride paper it is heated to drive off the water present, until it turns blue. You then dip it into the liquid you want to test. Water,or any liquid such as milk which contains water, will turn the paper pink (it may look white if there's not much cobalt chloride on it). Other liquids, e.g. gasoline, will have no effect.
