Compare the conductivities of solid sodium chloride and saltwater

Answer:

To be conductive a salt (nacl is a salt) needs to be as an ion. To be an ion it must be dissolved in solution. Solid NaCl is not an ion, so it is not conductive at all. Saltwater has Na+ Cl- ions floating around, and is more conductive.
