please can you answer questions part one
Vitamin C can be measured using a technique called titration. Because vitamin C is easily oxidized, we can use this chemical reactivity to detect it in solution. If we react vitamin C with iodine, the vitamin C is oxidized and the iodine is reduced. Iodine (12 molecules) form a purple complex with starch in solution, but reduced iodine, iodide, (I-) is colorless in the presence of starch. CH,OH CH,OH о о снон Η...
