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.

2. A 0.1000 g sample of KBrO3 was dissolved in dilute acid and treated with an excess of KI. BrO3 +91 +6H+ → Brº+ 313 + 3H20 The generated 13. required 11.92 mL of a Na2S2O3 solution to reduce it to 1. Use the above balanced equation and those found in the introduction to determine the molarity of the Na2S2O3 solution. 3. The following data was obtained for an iodometric titration of an ascorbic acid tablet. Mass of tablet: 1.2191...

2) A solution of I2 was standardized with ascorbic acid. The titration of a 10.00 mL aliquot of a stock solution made by dissolving 0.1050 g sample of pure ascorbic acid to a final volume of 100.00 mL required 25.32 mL of I2 to reach the starch end point a. What is the molarity of the iodine solution? b. How many mg ascorbic acid is required to react with 1.00 mL iodine solution?

Ascorbic acid (vitamin C, MM 176.124 g/mol)) can be determined using an iodometric back titration. A vitamin C tablet was dissolved in 60 mL of 0.3 M H2S04. To the dissolved tablet, 2 g of KI and 50.00 mL of 0.0105 M KIO3 were added, resulting in the formation of a dark orange solution indicating the presence of 13-. The resulting solution was titrated with 0.0685 M S2032- until the starch indicator turned purple. If the end point was observed...
