Go Green! – Iodine and Vitamin C
Go Green! – Iodine and Vitamin C

Experiments during Go Green classes

In the Go Green classes, the students performed an experiment with iodine and vitamin C. They learned that iodine changes the color of starch to navy blue, and adding vitamin C to the starch solution causes its discoloration. When ascorbic acid (which is vitamin C) reacts with iodine, it is oxidized and the iodine is reduced. The more vitamin C, the faster discoloration occurs.
