Sodium is a metal having free electrons; solid sodium chloride is not an electrolyte.
Solid sodium chloride doesn't conduct electricity.
Sodium Chloride solution (dissolved in water) conducts electricity, and molten Sodium Chloride conducts electricty, but dry crystal Sodium Chloride does not conduct electricity.
Sodium chloride conduct electricity only when is as an electrolyte: in water solution or melted.
Sodium chloride is not electrically conductive.
Solid sodium chloride is not an electrolyte.
No
No, sodium chloride does not conduct electricity in ethanol because ethanol is a nonpolar solvent that does not dissociate ionic compounds like sodium chloride. Sodium chloride only dissolves in ethanol, it does not ionize to form free ions that can conduct electricity.
Solid sodium chloride is not an electrical conductor.
Sodium chloride when dissolved in water forms an electrolyte that conducts electricity.
Aqueous sodium chloride contains dissociated ions which are free to move and conduct electricity. Dry sodium chloride does not conduct electricity because the ions are not free to move in a solid state.
Solid sodium chloride does not conduct electricity because the ions are in a fixed position and cannot move to carry an electrical current. It is only when sodium chloride is dissolved in water or melted that it can conduct electricity due to the mobile ions.
