Cobalt chloride

　　 Molecular formula：CoCl₂.6H₂O
　　　Molecular weight: 237.93
　　　Property：Pink or mauve crystal belonging to monoclinic system; density: 1.924g/cm3; stable under room temperature. Freely soluble in water, alcohol, aether, acetone and glycerin. It turns blue when heated and turns red in the moist air by cooling.. It changes into anhydride (blue power) when the crystal water is lost.
