Vitamin C Lab

Today, we started the Vitamin C lab. It is essentially testing different common drinks, such as apple juice and V8, for their vitamin C concentration. You add 20 drops of the liquid along with 3 drops of starch, and then you continue to add iodine drops until the solution remains a dark blue color. It was really interesting to see how different drinks that people drink every day have such different concentrations of this citrus-y vitamin even though they're all fruity.
