In the lab we learnt how much vitamin C is in different beverages. It allowed us to see if the nutrition facts where lying about how much vitamin C they where putting in these drinks.
In the lab we put 5ml of a starch mixture into test tubes. then proceeded to add a single drop of iodine. (Turned the liquid blue) Once they where mixed together, we added 10 drops of different liquids into different test tubes, and mixed it all together. (Changed colour) The more vitamin C there was in the liquids, the clearer the liquids became.
