Vitamin C reacts with iodine. In fact, iodine gains an electron from vitamin C. If there is more iodine in a solution than vitamin C then eventually the vitamin C will have no more electrons to lose to the iodine.Click to see full answer. Also asked, can iodine and vitamin C be taken together? Interactions between your drugs No interactions were found between iodine / potassium iodide and Vitamin C. This does not necessarily mean no interactions exist. why does vitamin C change the color of iodine? As long as vitamin C is present in the solution, the triiodide is converted to the iodide ion very quickly. However, when all the vitamin C is oxidized, iodine and triiodide will be present, which react with starch to form a blue-black complex. The blue-black color is the endpoint of the titration. Likewise, people ask, does vitamin C neutralize iodine? Vitamin C, more properly called ascorbic acid, is an essential antioxidant needed by the human body (see additional notes). Once all the ascorbic acid has been oxidised, the excess iodine is free to react with the starch indicator, forming the blue-black starch-iodine complex.Does citric acid react with iodine?Lemon juice contains citric acid which liberates elemental iodine from the iodide. Iodine and starch react to form a color which is dark purple or black, but given the small proportion of both iodide and flour in the salt, it appears blue.
