Electrolysis of Water Classroom Demo Apparatus

This innovative, portable, plastic, and safe Hoffman apparatus enables your students to demonstrate the process of electrolysis, allowing them 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 utilized 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 properties of the Hydrogen and Oxygen molecules.  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.  This apparatus is thus a versatile option for clear scientific classroom demonstrations.

Features:

• Apparatus based on the research of August Wilhelm von Hoffman demonstrates the process of electrolysis
• Allows students to visually observe the decomposition of water into its component elements, Hydrogen and Oxygen
• Includes a ready to use sodium sulfate solution that can be utilized in hundreds of demonstrations
• Gas collectors at the bottom of the apparatus allow students to observe some properties of the gaseous molecules
• Combine with an ammeter to facilitate a variety of additional classroom demonstrations
