Abstract
An iodine clock reaction that gives a colorless to black result similar to that of the familiar Landolt iodate-bisulfite clock reaction is described. The vitamin C clock reaction uses chemicals that are readily available on the retail market: vitamin C, tincture of iodine, 3% hydrogen peroxide, and laundry starch. Orange juice may be used as the vitamin C source to give an orange to black reaction.

Stephen W. Wright , Marsha R. Folger and Matthew A. Rice , Kyle B. Yeakel , Michael D. RoadruckJournal of Chemical Education2006 83 (10), 1473A sympathetic ink is described that uses a "clock reaction" between hydrogen peroxide and ascorbic acid (Vitamin C) to cause the writing to appear after predictable and controllable periods of time. The experiment is conducted using inexpensive chemicals ...
