Question

Why Solid sodium chloride does not conduct electricity

Answer 1

because it doesnot have free electrone and we know that those object conduct electricity which have free electrone.therefore sodiun chloride does mot conduct electricity insolid form

Answer 2

NaCl (common salt) is solid in state and solid ions or compounds don't conduct electricity. It needs to be either melted, molten or dissolved in a solution (i.e. water) first. This is because the electrons in a solid state won't be free to move to either the Cathode (-ve) or to the Anode (+ve). In a liquid state the electrons are free enough to move.
