1) In lab you are given 4 bottles, each containing about 5 grams of a white substance. Near the bottles are four labels indicating each bottle contains a high purity substance. Assume these labels belong to the bottles and that each bottle contains a single substance. The four bottles contain glucose (C6H12O6), sodium chloride (NaCl), aluminum oxide (Al2O3), and zinc sulfate (ZnSO4). Using your knowledge of solubility rules and electrolytic behavior, describe tests that you could conduct to determine which label belongs to which bottle. For these tests you may only use DI water, an aqueous solution of barium nitrate, and a conductivity tester to identify the substance in each of the bottles. Give the results you would expect for each test.
