Question

demonstration of strong electrolytes, weak electrolytes, and nonelectrolytes, Professor Popsnorkle used a lightbulb apparatus that showed how much a solution conducted electricity by the brightness of the lightbulb. When pure water was tested, the bulb did not light. Then Professor Popsnorkle tested the following aqueous solutions. Which one caused the bulb to burn the brightest?

Answer 1

Strong electrolyte

Step-by-step explanation:

Bulb doesn't light when water is used because water doesn't have any appreciable amount of ions for the conduction of electricity.

Strong electrolytes ionize almost completely in solution, thus providing a huge amount of ions to conduct electricity. More the number of ions, more charge is carried and hence greater current and thus leading to bulb glowing brighter.

Weak electrolytes ionize partially in solution, thus providing some amount of ions for carrying charge. This results in a small amount of current going to the bulb and hence the bulb lights up with very low intensity.

Non electrolytes doesn't ionize either and hence is similar to water. These have almost zero conductivity and hence the bulb doesn't light at all.
