Science Buddies: "Ask an Expert"

I am doing an experiment with iodine and oils. I am measuring the number drops of iodine it takes for it to discolour in certain oils.
I have found this experiment on a few websites, but they don't have any results or data which I can compare my results to.

Does anyone know of any sites? Thanks!

Hello Limobean.

If you search for "Iodine Value" you should turn up several web pages. For example, http://en.wikipedia.org/wiki/Iodine_value. This page gives the Iodine Value for several oils.

Thanks, but my school doesnt have the materials to do the experiments to calculate iodine value and they won't order it.

Limobean,

I'm confused. In your first message, you say, "...they don't have any results or data which I can compare my results to." This suggests that you have results, but in your last message, you say you don't even have materials. Please explain.

You can get the materials easily. You need just iodine, oils, and a method to measure the amounts of oil and iodine used in each test. You can buy measuring tools at any kitchen supply store. Iodine can be obtained, for example at http://www.amazon.com/J-CROWS%C2%AE-Lug ... rds=iodine.

Please let me know how your experiment progresses. WW
