How Do You Make Hydrogen From Water Electrolysis?
Water electrolysis is the separation of liquid water into hydrogen and oxygen gas using electricity. Electrons supplied at one submerged electrode and taken up by another electrode facilitate the chemical reactions to change H2O into H2 and O2. The two gases each bubble up from its own electrode. You can then catch either gas in a submerged, upside-down container before the bubbles escape at the surface. Scrape the insulation off the ends of two pieces of copper wire. You don’t need any special tool. A knife or scissors will suffice. Tape one bare end of each wire to each terminal of a 9-volt battery with electrical tape. Submerge the free ends of the wires in a bucket of water. Gas should bubble off the bare end of each wire as soon as you submerge both bare ends. Submerge a beaker or test tube right side up so it fills with water. Turn it upside down with the mouth still under water so the water stays in the container. Place the container above the bubbling from the wire connected to
