In terms of bonding, arrangement of particles and availability of ions and/or electrons, explain why sodium chloride dissolves in water, does not conduct electricity as a solid, but does conduct electricity as a liquid.
-
The sodium and the chlorine in sodium chloride are bonded together 'ionically'.
This means that (when solid) the ions form a rigid 'lattice structure'.
Therefore, the ions can't move about to conduct any electric current.
However, when it is molten or dissolved in water, this rigid lattice structure is broken.
Now, the ions are free to move about and conduct any electric current passed through them.
Hope that helped :)
