How do you measure the amount of Vitamin C in orange juice?

Posted by admin on Sep 30, 2009

I found a difficult way on a website, saying something about using starch, but it doesn’t say how to measure it. I need to see which orange juice has more Vitamin C for a Science Project. My teacher wants me to research it by tomorrow, so best answer will be chosen soon. Thanks for the help!
