Iodine (I 2) reacts with ascorbic acid only and not citric acid. The reaction between I 2 and ascorbic acid is a redox reaction. Instead of loading a buret directly with I 2, we will need to generate I 2 in situ. I 2 can be formed from potassium iodate (KIO 3) under acidic conditions, according to the following chemical ...

WebFirst, we need to know the chemical formulas of ascorbic acid and iodine. Ascorbic acid is C6H8O6, and iodine is I2. The balanced chemical equation for the reaction between ascorbic acid and iodine is: C6H8O6 + I2 → C6H6O6 + 2HI Now, we can write the two half-reactions: Step 2/3 1. WebAscorbic acid, C 6H 8O 6, (MW = 176.12) is oxidized by iodine, to dehydroascorbic acid, C 6H 6O 6. The I 3-will be generated in situ by adding a known volume of a standard iodate, IO 3-, solution to a solution of ascorbic acid and iodide. The iodate oxidizes the iodide to form I 3-, which reacts in turn with the ascorbic acid. The excess I 3
