Common mistake
Common Misunderstanding of Conductivity
Students often think that molten ionic compounds conduct electricity because they are hot, rather than understanding that it is due to the presence of free-moving ions.
Emphasize that molten ionic compounds conduct electricity because the ionic bonds break, allowing ions to move freely and carry charge.
