exp.8 Quantification of Ascorbic acid in vitamin tablets Iodometric titration

I.Purpose

Ascorbic acid, commonly known as vitamin C, is an essential nutrient for humans, playing a critical role in various biological functions. Its presence in dietary sources contributes to the maintenance of good health, and its deficiency can lead to serious health issues, including scurvy. Due to its significant biological functions, the quantitative analysis of ascorbic acid in vitamin tablets is of utmost importance, ensuring that consumers receive the appropriate dosage and that manufacturers maintain quality standards in their products. The purpose of this study is to determine the concentration of ascorbic acid in vitamin tablets using iodometric titration, a reliable and widely used analytical method. Iodometric titration is particularly suitable for this analysis because ascorbic acid can act as a reducing agent, reacting with iodine in a well-defined stoichiometric manner. The reaction involves the oxidation of ascorbic acid to dehydroascorbic acid while the iodine
