![]() BUT, before that can actually happen, the Vitamin C quickly reacts and consumes the elemental iodine. In Reaction # 1 iodide ions react with hydrogen peroxide to produce iodine element which is blue in the presence of starch. During these reactions two forms of iodine created – the elemental form and the ion form. There are actually two chemical reactions going on at the same time when you combine the solutions. Keep pouring the liquid back and fourth between the cups. Pour solution A into solution B, and pour the resulting solution back into the empty cup to mix them thoroughly.Prepare “solution B” by adding 2 oz of water to 3 tsp of hydrogen peroxide and 1/2 tsp of liquid starch solution. ![]() ![]() Combine 1 tsp of the vitamin C stock solution with 1 tsp of iodine and 2 oz of water.Label this as “vitamin C stock solution”. Make a vitamin C solution by crushing a 1000 mg vitamin C tablet and dissolving it in 2 oz of water.distilled water (tap water will work OK as well).This version of the classic “iodine clock reaction” uses safe household chemicals most people have on hand at home. There are actually a couple of simple chemical reactions going on at the same time to make this “clock reaction” occur. Two colorless liquids are mixed together and after a few moments the mixture turns a dark blue color. In may ways this experiment feels almost like magic. Try an at home version of this experiment using a few things you may have in your bathroom medicine cabinet. KeyBank Discovery Theater Special Features. ![]()
