Hi Giannamaria,

It sounds like you are interested in doing this Science Buddies project:

This is listed as an abbreviated project idea in Science Buddies, but it uses the method for measuring Vitamin C in this project:

The chemical you want is called Lugol's iodine solution. You can purchase a kit with all the materials for the project from the link on this page:

I hope that helps. Please post if you have more questions!
