Cobalt Chloride Hexahydrate Granular from pure cobalt broken cathodes. The item is 98+% minimum purity granular. Use for desiccant indicator, invisible ink, cobalt chemical preparation, etc. Cobalt (II) 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. 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(II) chloride gives a blue-green color in a flame. SOURCE: Wikipedia
