2 Cobalt chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl2. It is usually supplied as the hexahydrate CoCl26H2O, which is one of the most commonly used cobalt compounds in the laboratory. The hexahydrate is deep purple in color, whereas the anhydrous form is sky blue. A blend would be mauve. Because of the ease of the hydration/dehydration reaction, and the resulting color change, cobalt chloride is used as an indicator for water in desiccants. Niche uses include its role in organic synthesis and electroplating objects with cobalt metal. Cobalt chloride gives a blue-green color in a flame. Cobalt Chloride as an Indicator Cobalt Chloride starts out blue when it is dry. As it begins to absorb moisture, it turns purple. When it is fully saturated, Cobalt Chloride turns pink. Cobalt Chloride has been used in many capacities to indicate moisture levels. Paper can be infused with it in order to detect leaks, weather "predicting" novelty items were coated in it, and Silica Gel can be impregnated with it to indicate when the Silica Gel is fully saturated. Health and Safety Concerns with Cobalt Chloride Companies who use cobalt chloride have released Material Safety and Data Sheets (MSDS) that describe cobalt chloride as a skin and respiratory irritant. MSDS reports on the carcinogenic properties of cobalt chloride vary, some state that there is no risk while others say that it has caused cancer in laboratory animals. The warning label that comes with cobalt chloride is that any exposure can irritate the lungs and skin and long term

3 exposure can affect the heart, kidneys, lungs, and thyroid. Protective eyewear, gloves, respirators, and ventilation hoods are the recommended protection measures for handling cobalt chloride. Companies that use cobalt chloride as the indicator in their Indicating Silica Gel are putting their employees and consumers, as well as the environment, at unnecessary risk. British regulations have required that cobalt chloride be handled and disposed of as a hazardous material since Cobalt chloride, if not properly disposed of, can leach into the ground and and water supply, contaminating both. Although the UK has taken steps to protect against the possibly carcinogenic properties of cobalt chloride, similar measures have not been taken in the United States. Invisible Ink Cobalt chloride can be used to make invisible ink. Chemistry teachers Barker North and Norman Bland explained the procedure as long ago as 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. T.R.U.E. Test Cobalt chloride is used in the T.R.U.E. test, or Thin-layer Rapid Use Epicutaneous Test. Allergic contact dermatitis is an inflammation of the skin that can occur when people come into contact with a substance to which they are allergic. These substances, which include foods, plant pollens and metals, are called allergens. The

4 T.R.U.E. test is a patch test used on contact dermatitis sufferers to determine the causes of the inflammation. Three panels of surgical tape, or plaster, containing 29 allergens or allergen mixes, are applied to the sufferer's skin. Cobalt chloride is on panel 1 and is allergen 12. After a patient has worn the panels, if the skin shows signs of contact dermatitis where the panel 1, allergen 12 patch was, it is clear that cobalt chloride is the cause. Physicians can then advise the patient about avoiding contact with things that contain the compound. Computer Memory Devices Because of the magnetic properties of cobalt, it is useful as a coating for computer memory storage devices. There are two main types of coating, hard and soft. The latter has very rapid response, allowing fast data storage and retrieval. The hard magnetic coatings are usually alloys of 20 percent nickel and 80 percent cobalt. 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. An electric field is used to transfer the nickel and cobalt chloride ions from the solution onto an immersed object, thereby depositing a thin layer of nickel-cobalt upon it. Other Uses 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.
