Sodium chloride (NaCl) conducts electricity when dissolved in water, indicating it is composed of ions. Upon dissolution, NaCl dissociates into sodium ions (Na⁺) and chloride ions (Cl⁻), which are free to move in the solution, allowing it to conduct electric current. This behaviour confirms its ionic nature.
OR
Sodium chloride (NaCl) is formed through the transfer of an electron from sodium to chlorine, resulting in the formation of Na⁺ and Cl⁻ ions, which are held together by ionic bonds.
