In the electrolysis of molten cobalt (iii) iodide, molten metallic cobalt, Co(l) is formed at the cathode.

What are the products of the electrolysis of cobalt (iii) iodide?

The products of the electrolysis of molten cobalt (iii) iodide are cobalt and iodine gas.

The electrolysis reaction equation is given below:

  • [tex]CoI_3 (l) ---> Co (l) + I_2 (g)[/tex]

At the cathode, cobalt (iii) ions accepts electrons and are liberated as molten metallic cobalt as shown in the equation below:

  • [tex]Co^{3+} + 3e^{-} \rightarrow Co (l)[/tex]

Therefore, in the electrolysis of molten cobalt (iii) iodide, metallic cobalt is formed at the cathode.
