Hoffman Apparatus shown on the
right is normally used for water electrolysis. Hydrogen and oxygen
gases formed in tubes can easily be measured because both tubes
Water analysis can also be
performed with less complex devices that you can assemble at home
or at your school lab.
You perform a water analysis
experiment to find the answer to any of the following questions:
What gas will be produced in an anode? What gas will be produced in
What is the ratio of produced gases? How do ionic compounds help
the electrolysis of water? How does electrolysis of water affect
the pH of water in or around electrodes?
