Electrolysis lab leads students to splitting water into its gases

Students in Advanced Chemistry built an electrolytic cell to split water into its gases as part of its electrolysis lab project in class.

Here’s senior Conner King (North American Martyrs) with the explanation: “We made an electrolytic cell, and we had wires running into an anode and a cathode tube. And we had, we were separating water into hydrogen and oxygen gas. The oxygen gas turned into a precipitate of oxidized copper, which is rust. And then hydrogen gas came up in the other tube. And we had a wooden splint that we lit on fire and to cause a combustion reaction in the hydrogen tube.”
