vitamin c

I just wanted to ask if I can use iodine crystals in place of Lugol's iodine solution for the titration. I am doing the project to determine the amount of vitamin c in different fruits and vegetables. Please reply before 16May,2013.

Hello crazyabtscience,

Yes, if you have iodine crystals you can prepare your own solution. Pure iodine is not very soluble in water, so it's a little more complicated than just mixing iodine and water. You can find several recipes online.

Please be sure to read precautions in handling iodine crystals and take care.
