. To investigate the order of the reaction with respect to iodide label 5 conical flasks
or beaker and add all the reagents except hydrogen peroxide according to the
volumes shown in Table 1. Add 1 ml of starch solution (4 g starch in 1 L) to each of
the resulting solutions.
2. The last solution to be added is the hydrogen peroxide. At this point the stopwatch
is started.
3. Record the time taken for the solution to turn blue-black.
