Government and industry analysts routinely measure the quantity of ascorbic acid (vitamin C, C6H8O6) in commercial products such as fruit juices and vitamin tablets. The ascorbic acid reacts with excess iodine, and the amount of I2 remaining is determined with sodium thiosulfate (Na2S2O3). It is suspected by the Montreal Fraud Division that a prominent natural foods importer is defrauding his customers by claiming that his vitamin C tablets contain 45% of the active ingredient ascorbic acid. In one analysis, a...

Ascorbic acid or Vitamin C is a simple compound with the following chemical formula C6H8O6. Besides being an acid, it is also a reducing agent. One method for determining the amount of vitamin C in a sample is to titrate it with a solution of bromine, Br2, a good oxidizing agent based on the following chemical equation: Br2 (aq) + C6H8O6 (aq) --> 2HBr (aq) + C6H6O6 (aq) Suppose a 1.00-g “chewable” vitamin C tablet requires 27.85 mL of 0.102 M...

Ascorbic acid, or vitamin C (C6H8O6, molar mass = 176 g/mol), is a naturally occurring organic compound with antioxidant properties. A healthy adult’s daily requirement of vitamin C is 70-90 mg. A sweet lime contains 2.81×10−4 mol of ascorbic acid. To determine whether the ascorbic acid in a sweet lime meets the daily requirement, calculate the mass of ascorbic acid in 2.81×10−4 mol of ascorbic acid. Express the mass in grams to three significant figures.

ascorbic acid (vitamin C, MM= 176.126 g/mole) is a reducing agent, reacting as follows: C6H8O6 ----> C6H6O6 + 2H+ + 2e- the concentration of ascorbic acid can be determined by oxidation with a standard solution of I2 (2 I- ---> I2 +2e-). A 200.0 mL sample of citrus fruit drink is acidified and 10.00 mL of 0.0500 M I2 is added. after the reaction is complete, the excess I2 is titrated with 38.62 mL of 0.0120 M Na2S2O3 according to...

Calculate the weight percent of ascorbic acid in a tablet of Vitamin C from the following data: A 100 mg sample of a crushed Vitamin C tablet was dissolved in 40 mL of H2SO4 and 20 mL of water. Two grams of KI and 35 mL of 0.0107 M KIO3 solution was added, and the mixture titrated to a starch endpoint. The titration required 12 mL of 0.0790 M thiosulfate solution.
