If %FFA (as Palmitic acid) is 5.22% for a 5 g oil sample. What is the volume of 0.1N NaOH required to titrate the oil sample? If the volume of 0.1N NaOH required to titrate blank is 0.2 mL and the molar mass of Palmitic acid is 256.43 g/mol. 2. Which one of these statements is incorrect? a. Unsaturated fats are more reactive than saturated fats because they react easily with oxygen from the air. b. Saturated fats are more reactive than unsaturated fats because they are easily hydrogenated. c. Unsaturated fats are less reactive than saturated fats because they are very stable toward the photo-oxidation. d. The carbon-carbon double bond in the saturated fats is stable toward oxidation. e. (a) and (b) are incorrect f. (b) and (c) are incorrect g. (a) and (c) are incorrect h. All these statements are incorrect. 3. You have titrated an oil sample and used 6.2 mL of 0.01 N sodium thiosulfate (Na2S2O3) solution to reach the endpoint for the oil sample and 1.2 mL of 0.01 N Na2S2O3 to titrate the blank. The weight of the oil sample is 2 grams. Calculate the peroxide value (PV) of the oil sample in milliequivalents per kilogram (meq/kg). a. 12.5 meq/kg b. 25 meq/kg c. 50 meq/kg d. 100 meq/kg 4. What is the indicator used in the titration of peroxides to determine the peroxide value and what is the color at the endpoint? a. Starch, blue b. Starch, colorless c. Phenolphthalein, colorless d. Phenolphthalein, pink. Read more
