Description

Safely display the roles of temperature and
concentration in chemical reactions. You’ll mix one
colourless solution with another. In a few seconds,
the solution will suddenly turn dark blue. Increase the
temperature of the solution, and the reaction occurs
more rapidly. Dilute one of the solutions, and the
reaction occurs more slowly. This modified version
of the typical clock reaction uses safer chemicals to
demonstrate the impact of changing temperature
and concentration upon the outcome of chemical
processes.
