The iodate turns the ki solution to iodine i2.

Determination of vitamin c by redox titration with iodate. As the iodine is added during the titration the ascorbic acid is oxidised to dehydroascorbic acid while. The titration can be performed using just iodine solution and not iodate but the iodate solution is more stable and gives a more accurate result. The redox reaction is preferable to an acid base titration because a number of other species in juice can act as acids but relatively few interfere with the oxidation of ascorbic acid by iodine.

C standardizing an iodine solution. Vitamin c more properly called ascorbic acid is an essential antioxidant needed by the human body see additional notes. Vitamin c more properly called ascorbic acid is an essential antioxidant needed by the human body see additional notes.
