Caption: Electrical conductivity. Ammeters (lower right and left) showing different electrical conductivity in weak and strong acids. The weak acid (ethanoic or acetic acid, left-hand beaker) conducts a smaller electric current (0.03 amps) than the strong acid (hydrochloric acid, right-hand beaker, 4.47 amps). This is because the hydrochloric acid dissociates more readily into ions than ethanoic acid. These ions carry electric charge between the electrodes (black) dipped into the acids. Electrical power is provided by the power pack behind the beakers. The connecting wires form circuits by connecting the power pack, ammeters and electrodes.
