I pledge my honor that I have abided by the Stevens Honor System. 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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
