by

Cobalt(II) chloride , with the chemical formula CoCl2, is a cobalt and chlorine inorganic compound. Let us have a look at the uses of Cobalt(II) chloride (CoCl2).

Cobalt(II) chloride combination produces multiple hydrates of CoCl2.nH2O and generally has several uses like-

  • Nanotechnology
  • Sports
  • Usage in Perovskite Solar cells
  • Invisible Ink
  • Water Desiccant Indicator

Let us focus on the uses of Cobalt (II) chloride in detail in this article.

Nanotechnology

  • CoCl2 is used to synthesize ionic liquids based on the coordination number where bond length between Co and Cl can be extended.
  • CoCl2 is used in making nanowires by the process of electrodeposition.

Sports

  • Cobalt chloride (CoCl2) is used as a well-known chemical inducer of hypoxia-like reactions, including erythropoiesis.
  • Cobalt chloride (CoCl2) is administered by athletes.

Usage in Perovskite Solar cells

Cobalt chloride (CoCl2) is used in perovskite solar cells with SnO2 to increase charge extraction and creates more favorable energy level alignment.

Invisible Ink

  • Cobalt chloride (CoCl2)is used to make invisible ink.
  • Cobalt Chloride (CoCl2) glows blue when heated and turns invisible when it cools.

Water Desiccant Indicator

  • Cobalt Chloride (CoCl2) is used as an indicator for water in desiccants.
  • Cobalt Chloride (CoCl2) readily undergoes hydration and changes color when dehydrated.

Conclusion

Cobalt chloride (CoCl2) is used in many different branches of research and technology. In addition to being a component of solar cells, it can be used as water desiccants and invisible ink.
