Iodine clock reaction activation energy

Webfinal reaction marking when the reaction series is completed. The analogy is that it is like an alarm clock. The clock runs for a time, and then the alarm sounds. The running clock is like the first reaction above, the “alarm” is like the combination with starch. 2. Rate of reaction is defined as how fast reactants are used up or products ... WebFirst Solution: Starch, Water. Second Solution: Iodine Salt, Reductant, Water. Third Solution: Oxidant, Acid, Water. Once the solutions mix, the reaction begins. The most common variant of the Iodine Clock Reaction uses sodium thiosulfate (Na 2 S 2 O 3) as the reductant and hydrogen peroxide (H 2 O 2) as the oxidant.
