Question

______ conducts electricity by the movement of ions.

Options

• Molten iron

• Molten sodium chloride

Answer 1

Molten sodium chloride conducts electricity by the movement of ions.

Explanation:

Electrolytes (or Electrolytic solutions/molten salts) conduct electricity by the movement of ions

When dissolved in a solvent (like water) or in a molten state, these compounds dissociate into positively charged ions (cations) and negatively charged ions (anions), which move freely to conduct electricity.
