Cobalt chloride (CoCl₂) is an inorganic compound that typically comes in powder form.
Properties
Chemical Formula: CoCl₂
Appearance:Anhydrous CoCl₂: Blue powder.
CoCl₂·6H₂O (hexahydrate): Pink or reddish powder or crystals.
Solubility: Anhydrous CoCl₂ Soluble in water, alcohol, and acetone.
CoCl₂·6H₂O (hexahydrate) The color changes from blue (anhydrous) to pink (hydrated) when dissolved in water, which is a well-known colorimetric property.
Molar Mass: 129.83 g/mol (anhydrous).
Melting Point: 724°C (anhydrous).
Boiling Point: 1,049°C (anhydrous).
Applications
Humidity Indicator: Cobalt chloride is often used as a humidity indicator because it changes color depending on the amount of water it contains (blue in dry conditions, pink when exposed to moisture).
Biological Research: Used in cell studies and biochemical research as a source of cobalt ions.
Catalysis: Serves as a catalyst in some chemical reactions, particularly in organic synthesis.
Electronics: Employed in electroplating and in the production of cobalt-containing chemicals.
