Surface treating metal is another common industrial use of the compound. It is also used for electroplating, particularly for plating objects with cobalt metal. Cobalt (II) chloride is said to be kinetically inert.Ĭommercially, cobalt (II) chloride is often used to make sealants, adhesives, and glues. It’s a necessary precursor for both cobaltocene and tetralykl. A common precursor to other cobalt compounds, CoCl 2 is readily oxidizes and often used in the presence of a catalyst. It’s also a powerful intermediate compound. Cobalt (II) chloride is a weak Lewis acid. It’s often used as an indicator for water desiccants. Noah Chemicals supplies cobalt (II) chloride anhydrous with 99% purity in several amounts.Ĭobalt chloride changes color in response to humidity, hence the color differential between its anhydrous and hexahydrate forms. It is generally supplied in bead form and should be handled carefully as it is a suspected carcinogen. Noah Chemicals supplies ACS Reagent grade cobalt (II) chloride hexahydrate.Ĭobalt (II) chloride anhydrous, also known as Cobaltous Chloride, is a beautiful sky blue color. Hexahydrate is by far one of the most common forms of cobalt used in laboratory settings.
Harmful if swallowed or applied directly to skin, it is generally shelf-stable at room temperature. The chemical formula for the compound is CoCl 2 ♶H 2 O. The hexahydrate of cobalt (II) chloride is bright pink. The compound is most often supplied as cobalt (II) chloride hexahydrate or as cobalt (II) chloride anhydrous.
Its chemical formula is CoCl 2 and its molecular weight is 129.833 g/mol. Cobalt (II) chloride is one of the most common forms of chloride found the lab today.
