Sodium chloride is made up of clear, colorless crystals. A solution of sodium chloride in water is a good conductor of electricity. Which statement describes sodium chloride?

A sodium chloride solution conducts electricity because it contains mobile charged particles. When sodium chloride dissolves in water, it separates into sodium ions (Na⁺) and chloride ions (Cl⁻). In the solid, these ions are held together by ionic bonds, so choice A is correct.
