Application

Cobaltous Chloride Hexahydrate is commonly employed as a humidity indicator due to its color-changing properties (blue when anhydrous, pink when hydrated). It acts as a catalyst in organic synthesis, particularly in oxidation and polymerization reactions. Additionally, it serves as a cobalt source in electroplating baths and ceramic pigments. Researchers also use it in trace metal analysis and as a nutrient in cell culture media for cobalt-deficient studies.
