Why does molten sodium chloride conduct electricity but solid sodium chloride does not?
Molten and Aqueous Sodium Chloride conduct electricity because the ions are free to move where as is a solid they have no free room. This is the same for magnesium chloride. In aluminium chloride and phosphorus chloride the solid doesn’t conduct electricity because the ions aren’t free to move. In liquid form they have converted into a covalent form, and so don’t conduct either. All of the other chloride dont conduct electricity because they have no free ions or electrons when solid or liquid.
