How the Conductivity Demonstration Works
The bulb in the holder is wired in series with a power supply and two electrodes, and the electrodes are dipped into the liquid under test. A solution of an ionic substance such as sodium chloride, or a dilute mineral acid, carries current by the movement of its ions, and the bulb lights. Sugar solution and distilled water contain too few ions, so the bulb stays dark, while a weak electrolyte such as dilute acetic acid gives only a dim glow. Switch off before lifting the electrodes out, and rinse them before testing the next liquid.
