Not a Scientist Posted February 4, 2008 Report Share Posted February 4, 2008 My daughter is in 3rd grade. Her science project is to determine which juices have the most Vitamin C. We performed the project by adding different juices to the iodine mixture, but it took over 100 drops of each juice to make the blue/purple color completely disappear. Does anyone know if this is correct? I was expecting to only need a few drops. I may have done something wrong. Thanks. Quote Link to comment Share on other sites More sharing options...
