Electrical conductivity, 2 of 4. A solution conducts electric current when it contains charged particles (ions). A circuit consisting of a battery, two electrodes (copper and graphite) in a jar, and a light bulb is used to test electrical conductivity of different solutions. When table salt (sodium chloride, NaCl) is added to water, the bulb lights up. Table salt dissociates into Na+ and Cl- ions that carry electric charges in the solution. | |
