The number of drops they added to make a 10 milliliter sample of the blue indophenol indicator become colorless are given here: 8 drops of Overly Orange 13 drops of Luscious Lemon 33 drops of Fruitsnap (and it still didn't change color). Does Overly Orange or Luscious Lemon contain a higher concentration of vitamin C? What is the evidence?
Reference answer: Overly Orange takes fewer drops to change the color of indophenol so Overly Orange has a higher concentration of vitamin C.

Student answer: Overly Orange, OO, has more because it has less drops. Luscious Lemon does not have as much as OO because of the drops.

Student answer: Overly Orange contains higher concentration because the one with the least drops contains most vitamin C. Orange 8, Lemon 13.
