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?

Sodium chloride is an ionic compound: it consists of positively charged sodium ions and negatively charged chloride ions held together by ionic bonds. When it dissolves in water, these ions can move freely and carry electric charge, so the solution conducts electricity. The covalent and metallic bonding choices do not describe sodium chloride.
