Question 1

[Maximum number: 2]

Iron(II) sulfide can be produced by heating powdered iron and sulfur together.

A student hypothesised that iron(II) sulfide is ionic and therefore can be converted back to iron and sulfur by electrolysis of the molten salt, using inert electrodes.

Annotate the electrolytic cell with the terms anode and cathode, and show the direction of ion movement.
