Answer
(a) Copper does not undergo chemical decomposition due to flow of electric current through it. Hence, copper is a good conductor of electricity but it is a non-electrolyte.
(b) In solid sodium chloride, ions Na+ and Cl- are not free to move due to the strong electrostatic forces. Hence, solid sodium chloride does not allow electricity to pass through it.
