How can you seperate hydrogen and oxygen in water?
“The electrolysis of water is a simple method of producing hydrogen, although the resulting hydrogen necessarily has less energy content than was required to produce it. A low voltage current is run through the water, and gaseous oxygen forms at the anode while gaseous hydrogen forms at the cathode.” This means you need a water container with two wires seperated. When you run a voltage through them the negative side will have the hydrogen bubbles forming on it and the positive side will have oxygen bubbles forming on it.
