In demonstrations of strong and weak electrolytes and nonelectrolytes, a lightbulb apparatus that shows how much a solution conducts electricity by the brightness of the light is often used.When pure water is tested, the bulb does not light.Which of the following aqueous solutions causes the bulb to burn dimly but not brightly?

Acetic acid is a weak electrolyte, meaning it only partially dissociates in water. This partial dissociation allows for some electrical conductivity, but not as much as a strong electrolyte like NaCl, which would cause the bulb to burn brightly. Isopropyl alcohol, fructose, and methanol are nonelectrolytes and do not conduct electricity well, so they would not cause the bulb to light up significantly.
