okay so for my science fair project, im doing an experiment to see the changes in vitamin c after oranges have been stored in different places. I don't understand how to make the indicator solution or where to get the things needed to make it. Can someone please help me?

Re: titration HELP!!!!
Hello and welcome to the forum. Which indicator solution are you making? I found two that are very similar here http://www.wikihow.com/Make-a-Vitamin-C-Indicator and here http://www.ars.usda.gov/IS/KIDS/FAIR/method.htm. Are these what you are making? The easiest one is the cornstarch and iodine one. Cornstarch can be found at any grocery store, and the USDA site suggests that drugstores carry 2% iodine solution. Let us know if you need more information.
