## Chemistry 10th Edition

In order to check the presence of a strong, weak or nonelectrolyte in a solution, we can put two metal electrodes with a light bulb within the circuit in the solution. The light bulb will glow according to the concentration of ions in the solution. $Na_2SO_4$: Glows brightly, strong electrolyte. $HCN$: Glows dimly, weak electrolyte. $CH_3COOH$: Glows dimly, weak electrolyte. $CH_3OH$: Does not glow, nonelectrolyte. $HF$: Glows dimly, weak electrolyte. $HClO_4$: Glows brightly, strong electrolyte. $HCOOH$: Glows dimly, weak electrolyte. $NH_3$: Glows dimly, weak electrolyte.
