In this lab, we had 6 test tubes per group, in each test tube we poured 5ml of starch solution and one drop of iodine. Then we proceeded to add a different type of pop/juice in to each of the test tubes. This is what they looked like before the juices were added.

We poured the drinks in order starting from left to right, the first substance was pure Vitamen C, this substance had no particular smell and was completely clear, after we mixed it in we noticed that the substance turned from blue to clear again. The second substance was blueberry juice, this substance was red and smelled like fruits its daily vitamin C content was 15%, after we poured it in we noticed that the substance got more clear, after some time we noticed that the liquid turned pink. The third substance was strawberry banana juice, this substance was a thick orange substance that smelled like oranges, daily Vitamen C content was 80%, after inserted the substnce turned into a greyish turquoise substance. The fourth substance was 7up, this substance looked like bubbly water and smelled like lemons, 0% vitamin C, after inserted we saw that there was absolutely no change. The fifth substance was iced tea, this substance had a light yellow tint and smelled like lemons, Vitamen C 140%, after inserted we noticed that th substance went completely clear with a very slight blue tint. The sixth and last substance was Blue Gatorade, vitamin C 0%, after inserted the liquid turned slightly clearer. This is a picture after the experiment.

After the experiment we noticed that the more calcium C these substances had, the clearer the liquid got.
