Introduction to Cobalt Chloride

Cobalt Chloride, or CoCl2, is a compound of cobalt and chlorine. It is more correctly known as cobalt (II) chloride or cobalt dichloride.CoCl2 is red or amaranthine crystal, easily soluble in water, soluble in ethanol, aether and propanone. The compound is blue when it is anhydrous, or contains no water. When wet, cobalt chloride is the color magenta.Cobalt chloride is usually supplied as the cobalt chloride hexahydrate CoCl2·6H2O, which is one of the most commonly used cobalt compounds in the laboratory.
Due to its chemical properties, including its ability to change color when it comes into contact with water, cobalt chloride has several uses.Cobalt Chloride can be used to make invisible ink.If you dissolve cobalt chloride in water and use the substance to draw or paint on a sheet of white paper, the markings will be almost invisible when the substance dries. To make the markings visible again, you simply have to warm the paper in front of a source of heat. Because of the magnetic properties of cobalt, it is useful as a coating for computer memory storage devices.Electroplating using the chlorides of these metals is one of the ways used to coat the devices. The process involves manipulating the metal ions in solution. Ions are atoms or molecules with positive or negative charge.In addition, Cobalt and Cobalt Chloride may also be used in the making of building materials, paints, pigments and printing inks, vitamin B12 supplements, tattoo inks, soaps and silica gel.
