Question

What substance is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(l), and molten magnesium iodide, mgi2(l)? assume standard conditions. express your answer as a chemical formula?

Answer 1

The substance that is produced at the cathode during the electrolysis of a mixture of molten calcium bromide, cabr2(I), and molten magnesium iodide, mgi2(I), can be expressed as Ca2+ + 2eâ’ --> Ca. At the anode, the substance can be expressed as 2Brâ’ â’ 2eâ’ --> Br2. At the cathode for magnesium iodide can be expressed as Mg2+ + 2 eâ’ --> Mg, and 2 Iâ’ â’ 2 eâ’ --> I2 at the anode.
