Suppose you standardize a Na2S203 solution by dissolving 25.0 mg of KIO3 in acid and allow it to react with excess KI. The triiodide produced is then titrated with Na2S203 solution, requiring 30.00 mL to reach the starch/triiodide end point. Determine the molarity of the thiosulfate solution considering the following reaction: 103 +1 + H* → 13 + H20 2- + SO 2 3 2- →1 + $,°% 3 4 6

Calculate the amount of caffeine extracted from coffee beans using 1.0215g of the sample. The volume of 0.0252N H2SO4 added to the extract was 25.4 mL, the excess titrated by 21.75 mL of 0.02115N NaOH. Each mL of 0.02 N H2SO4 is equivalent to 3.8858 mg of caffeine (C9H10O2). The percentage of caffeine is:
A certain lipid sample consists of a wax of unknown molecular weight and composition. It is known, however, that the 2 groups are the same fatty acids. In order to investigate this, saponification and iodine numbers were used. A 3.000 g wax sample was placed under reflux with 20.00 mL of 0.7000 M KOH (56.1056 mg/mmol). It was then back-titrated using a 0.3500 M HCl titrant that required 23.91 mL to the phenolphthalein endpoint. To further characterize this, a 0.100 g sample was titrated for its iodine number. This consumed 3.50 mL of 0.100 N thiosulfate titrant. (Iodine: 126.905 g/eq) a) What is the saponification number of this wax sample? b) What is its Iodine number? c) How would you describe this in terms of unsaturation? d) Given that it is a wax, what is the general structure of this lipid? e) What will be the MW factor for this lipid? f) What is the average MW of the lipid? g) Given the table of molecular weights below, what is the possible identity of the wax?

5 The amount of ascorbic acid, C6HSO6, in orange juice was determined by oxidizing the ascorbic acid to dehydroascorbic acid, C6H6O6, with a known excess of I3, and back titrating the excess Is with Na2S2O3. A 5.00-mL sample of filtered orange juice was treated with 50.00 mL of excess 0.01023 M I3. After the oxidation was complete, 13.82 mL of 0.07203 M NazS2O3 was needed to reach the starch indicator end point. Report the concentration of ascorbic acid in milligrams per 100 mL.
