This innovative, portable, plastic, and safe Hoffman apparatus enables your students to actually observe the decomposition of water into its two components of Oxygen and Hydrogen. The ready to use neutral sodium sulfate solution can be used hundreds of times, alternatively by adding an indicator one can visually follow the pH changes at the two electrodes. Gas collectors make it possible to examine some of the Hydrogen and Oxygen properties. An optional ammeter provides a higher level of scientific investigation, such as calculating the ideal gas constant R, or the charge of a single electron.
