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. WebThe first reaction produces I 3-. When I 3-comes in contact with starch (in reaction three) it produces a characteristic blue/black color. However, before that can happen S 2 O 3 2-reacts with it to produce colorless products (in reaction two). Because reaction two is much faster than reaction three, the third reaction won’t take place until ...
