Answer:
True: Sodium Chloride Solution will conduct Electricity.
Explanation:
When Sodium Chloride is in solid form it fails to conduct current, But when it is dissolved in water it dissociates to produce a Na⁺ and Cl⁻ ions which are current conducting between two electrodes.
NaCl ₍s₎ + H₂O → Na⁺ ₍aq₎ + Cl⁻₍aq₎
