Cobalt chloride test paper. Cobalt chloride paper strip is used to test vapor coming out of a test tube. When water is present, cobalt (II) chloride (CoCl2) test paper changes its colour from blue (anhydrous CoCl2) to purple (dihydrate CoCl2 2H2O) to pink (hexahydrate CoCl2 6H2O). Therefore it is often used as a water (humidity) detector. | |
