Ryan Mccullough · Answer 1

NaCl when in solid state does not conduct electricity while it does in aqueous solution.

Explanation:

NaCl (or what we call common salt) first needs to be either melted or dissolved in a solution for it to conduct electricity. The reason for this is that electrons in a solid state does not have enough freedom to move to either the Cathode (-ve) or to the Anode (+ve). So in a liquid state the electrons are now free enough to move.
