<p>Solubility - Experiment 2</p><p>Pre-Lab: Theory - 5 points 7 MSDS - 3.5 10 Structures – 2.5 4 Chem. Rxns (part D) - 4 4 Data Tables - 4 19 points Final Report: Data tables filled in - 14 points 15 questions – 15 (For ques 1-2 answers for each – your prediction and the Merck Index answer.) Part A: 1. Give the polarities of the 3 solids. - 3 2. In which of the 9 pairs could H-bonding at least partially account for the solubility? - 3 3. Diagram the H-bonding between one of these pairs - 2 4. Explain your solubility result for benzophenone and water.- 2 5. Explain your differing results for benzophenone and biphenyl in CH3OH. - 2 Part B: 1. What trend can you find in the alcohols' solubility in water? In hexane? - 2 2. Explain the reason for this trend in water and in hexane. - 2 Part C: 1. Which pairs could theoretically H-bond to each other? - 2 2. In which pair does H-bonding account for the solubility result? - 2 3. Explain the solubility test results for each one of the remaining pairs; discuss polarities - 4 Part D: 1. What did you observe in the tube of benzoic acid and water? - 1 2. " " " " in the tube of benzoic acid and HCl? - 1 3. What did you observe when NaOH was added to benzoic acid? - 1 4. What was formed that would account for this result? Explain reason for solubility result. - 2 5. What happened when HCl was added to the tube with NaOH and benzoic acid? - 1 6. What formed that would account for this result? Explain reason for solubility result - 2 Part E 2a: 1. What solid and which 2 liquids were you assigned? 2. Draw the structures of the 3 and state the polarity of the organic compounds. - 5 (HCl and NaOH are 100% ionized in water - we don't use the term polarity here!) 3. Which of your 2 liquids would the solid dissolve in? Justify your answer. If a chemical reaction occurs, write the reaction. - 3 4. The 2 liquids are immiscible. Which one will be the top layer? Justify your answer by giving the densities of both liquids - 3 </p><p>Total Points: 92</p>
