    What's the difference in the ability of solid sodium chloride and molten sodium chloride to conduct electricity in terms of their structures? Thanks

    In the molten solution, the negative chlorine ions can conduct electricity because they're able to move around and carry the current.

    In the solid, the ionic lattice structure is fixed and the ions are unable to carry the electric current.

    Solid sodium can't conduct electricity because the ions are in a lattice and are not free to move, whereas in molten the negative ions (chlorine) ions go to anode(Positive) and the positive ions (sodium) ions go to cathode(Negative)
