Oxidation Reduction Titrations: The Indirect Iodimetric Analysis Ascorbic Acid Unknown Number 69 I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis‚ the oxidizing agent can be determined by a different means than titrating directly with standard iodide‚ because a high concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to
