CONDUCTIVITY TEST: GRAPHITE IN SODIUM CHLORIDE(AQ)<br />
Demonstrating A Simple Circuit<br />
Apparatus demonstrates a simple circuit incorporating a saline solution electrolyte and electrodes of pencil "lead" or graphite. The glowing light bulb shows that NaCl aq is a strong electrolyte and that graphite conducts electricity.
