Did You Know?

Hydrated cobalt (II) chloride is famous for its color-changing behavior, shifting from pink when hydrated to blue when dehydrated. This reversible transformation makes it a classic teaching tool for demonstrating hydration, equilibrium, and environmental moisture detection. Historically, cobalt chloride has been used in humidity indicators and invisible inks, helping students visually connect chemical structure with real-world applications.
