Thinking about potassium, we’re sure.
Starting in 1807, Sir Humphry Davy used electrolysis to discover a myriad of elements. He used this process to uncover what we now take for granted as potassium, sodium, barium, calcium, chlorine, and magnesium among others.
The process Davy’s used has largely remained unchanged and can be followed by you and your students using the following Electrolysis Apparatus Unit (N99-B-2637-040) found at NADA Scientific.
The electrolysis apparatus is used to demonstrate experiments in electrical charge/discharge and energy conversion. It features a main unit made of AS resin with fixed stainless steel electrodes, graduated test tubes (2), and a resin test tube holder. The compact design makes these units stackable for neat and easy storage.
If you’re looking for a suitable power source, it can also be purchased with the GENECON12 as a set to create the entire lab experience of separating water into its component gases.
