The student is now told that the four solids, in no particular order, are magnesium bromide (MgBr2), sugar (C6H12O6), benzoic acid (C6H5COOH), and sodium bromide (NaBr). 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.
