The student is now told that the four solids, in no particular order, are barium chloride (BaCl2), sugar (C6H12O6), benzoic acid (C6H5COOH), and potassium bromide (KBr). Assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 M solution in water will conduct electricity.
Rank from most conductive to least conductive. To rank items as equivalent, overlap them.
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.
