June 2023 NY Regents Chemistry Exam
47 Which aqueous solution has the greatest ability to conduct an electric current? (1) 0.10 M NaCl(aq) (2) 0.010 M NaCl(aq) (3) 0.10 M C6H12O6 (aq)
(4) 0.010 M C6H12O6 (aq)
Solution: Ionic compounds, when dissolved in water, dissociate to produce ions (charged) and can conduct electricity. NaCl is an ionic compound because it is composed of a metal and a nonmetal. The higher the concentration of the ionic solution, the more it will be able to conduct electricity.
