Final answer:

The answers detail the ions responsible for conduction, migration towards anode and cathode, and the corresponding half-cell reactions during electrolysis of fused CaCl2.


Explanation:

a. Which ions are responsible for the conduction of electricity through the molten salt?
For the electrolysis of fused CaCl2, the responsible ions are Ca2+ and Cl- as they are the charged particles that facilitate the flow of electricity.

b. Which ion migrates towards anode?
In this scenario, Cl- ions migrate towards the anode during electrolysis.

c. Which ion migrates towards cathode?
Ca2+ ions migrate towards the cathode during electrolysis.

d. What half-cell reactions occur at the anode and cathode?
The half-cell reactions are:
At the anode: 2Cl- - 2e- → Cl2(g)
At the cathode: Ca2+ + 2e- → Ca
