Answer 2

Answer:

Option (d) NaCl(s) is not a good conductor.

Explanation:

A conductor, or electrical conductor, exists as a substance or material that permits electricity to flow through it. In a conductor, electrical charge carriers, usually electrons or ions, move effortlessly from atom to atom when voltage exists applied.

• Solid NaCl exists as a poor conductor of electricity since the charged particles (ions) exist unable to move due to intense electrostatic forces binding them together. As a consequence, they exist unable to conduct electrical current.
• Copper exists as a good conductor than iron, which ensures current can pass via it more efficiently (and with less resistance). This exists as a material's intrinsic property.
• An electrolyte exists sodium chloride. It dissociates into Na+ and Cl- in solution. The cations exist attracted to the cathode and the anions to the ode as electrodes exist placed in the solution. NaCl solutions can conduct electricity because of this action, which induces a current.
• Strong NaCl exists also as an electrical conductor. Because of its mobile electrons, molten sodium stands as a fine conductor.

Hence, Option (d) NaCl(s) is not a good conductor.
