WebThe amber color is due to the presence of I ₂. When I - is present, it reacts with I ₂ and starch to produce a dark blue complex. This color fades as iodine is consumed. A very simplified explanation of this reaction is: 2 H I O X 3 + 5 H X 2 O X 2 I X 2 + 5 O X 2 + 6 H X 2 O gold. I X 2 + C H X 2 ( C O O H) X 2 I C H X 2 ( C O O H) X 2 + H ...

WebThe following equation shows the 1:1 reaction between Vitamin C (Ascorbic acid) and Iodine. C6H8O6 + I2 à C6H6O6 + 2I- + 2H+ Iodine (I2) solution is a brown solution and dissolved Iodide (I-) ions are colorless. Free iodine in the presence of starch makes an I2-Starch complex that is dark blue in color. If there is vitamin C, it will react with I2.
