POST-LAB REPORT FOR THE SOLUBILITY EXPERIMENT

I) Conclusion: Write the conclusions regarding your observations and results obtained from each part 2A, 2B, 2C, and 2D, separately. Separately describe and explain in your conclusions whether the experimental observations and results obtained from that part enabled you to confirm the solubility behavior of various compounds based upon what you had predicted and hypothesized before performing the experiment. (In your discussions, bring out the theoretical concepts on which solubility is based upon and tie them with their solubility behavior). (8 Points)

II) Part A Results: 1) Complete the following table by rating the solubility of each organic compound in the indicated solvents either as soluble, partially soluble, or insoluble. (9 Points)

Organic Compound

Water (solvent)

Methyl alcohol (solvent)

Hexane (solvent)

Benzophenone

Malonic Acid

Biphenyl

2) There should be a difference in the results between the solubilities of biphenyl and benzophenone in methyl alcohol. Explain why there is this difference. If no difference was observed, then predict which one should be more soluble and explain why. (4 points)

3) There should be a difference in the results between the solubility of benzophenone in methyl alcohol and its solubility in hexane. Explain this difference. If no difference was observed, then predict in which solvent, methyl alcohol or hexane would you expect the solubility of benzophenone to be greater and explain
