The general results, ... The clock reaction, however, allows the student to ... The molecular iodine, I2, produced in Step 2 reacts with the starch (not shown in the equations), to produce the deep blue-black solution. The color change indicates that the first reaction is complete and the second one has begun to take place.

Iodine Clock Reaction; A Study of the Effects of Concentration, Temperature, and a Catalyst on Reaction Rate; Introduction; ... Three general statements can be made by looking at the results from this experiment. (1) The reaction rate increases as concentration increases and decreases as the concentration decreases.
