Submission Date: September 28, 2006 Bench Number: F 1-8 Student Name: Gregory Bosch Jr. Email: [email protected] TA: ABSTRACT: The experiment was done in order to determine the amount of Vitamin C or Ascorbic Acid present in a Vitamin C tablet and in foodstuffs such as orange juice. To determine the amount of the vitamin C present in a substance, redox chemistry was utilized. The mass of ascorbic acid in the tablets was found to be about 8.12 X 10 -8 g and that in the foodstuff (orange juice) was found to be 1.27 x10 -2 g. KEYWORDS Ascorbic acid, vitamin C, Potassium Iodate, Potassium Iodide, starch, iodine, titration HCl INTRODUCTION A simple method utilized to determine Vitamin C content is to take advantage of its strong reducing properties. In the experiment, titration was used in order to measure the amount of Vitamin C in a tablet and various foodstuffs. The reaction takes advantage of the ability of the substance Vitamin C to reduce iodine to iodide ion. The iodine first generated by a reaction of iodate ion with an iodide ion in an acid
