Problem: A student tests four solids for their ability to complete an electrical circuit when dissolved in water by observing their ability to close a circuit containing a light bulb and obtains the following results:Which of the solids is a weak electrolyte when dissolved in water?An electrolyte is a substance that when dissolved in water, the solution will conduct electricity. A solution that conducts electricity well is said to contain a strong electrolyte. A solution that conducts electricity poorly even when a significant quantity of the solute is present contains a weak electrolyte. In contrast, a substance that does not conduct electricity when dissolved in water is a nonelectrolyte.Watch the video about the electrolytic properties of sodium chloride, NaCl, and sugar.

Which of the solids is a weak electrolyte when dissolved in water?


An electrolyte is a substance that when dissolved in water, the solution will conduct electricity. A solution that conducts electricity well is said to contain a strong electrolyte. A solution that conducts electricity poorly even when a significant quantity of the solute is present contains a weak electrolyte. In contrast, a substance that does not conduct electricity when dissolved in water is a nonelectrolyte.
