Lab Report Grading Checklist

2 Experiment 5 GradingCContent of the Report 70 % of grade1 Questions of the Week:Part A: What can solubility in acidic and/or basic aqueous solutions tell us about structures of2 organic molecules?Claim: Initial claim clearly deals with the QOW— Conclusion on which functional groups might be3 more soluble in acid than in water and which more soluble in base than in water.4 Warrant: The basis for classifying compounds as likely to be more soluble in acid or base than in water.5 Part B: How can we use pH effects on solubility to separate mixtures of compounds?6 Claim 1: Identification of compounds used for separation in Part B.Warrant 1: Characteristics used to choose compounds (e.g. Acid vs. Base, Acid vs. Neutral or Base vs.7Neutral)8 Characteristics based on solubility data from Part A.9 Experimental Plan:10 Presents a plan for the work to be done in the laboratory and addresses QOW Part A11e.g Determine solubilities of a series of compounds in water, acid & base and analysis of data tocorrelate solubilities with functional groups present in the molecules.12 Presents a plan for the work to be done in the laboratory and addresses QOW Part BCreate a mixture of two compounds from those studied in Part A that can be separated using an acidbaseextraction and separate them. Judge the effectives of the 13separation.14 General rather than dealing with specifics. (i.e. No specific compounds or procedure steps included.)15 Summary of Results: (See Lab Manual Part III. p. 19-20)16Data table with names, structures and modes of the all class solubility results in 1 M HCl vs. waterfrom Part A.a.
