Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.
Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
