How Do You Make Hydrogen By Electrolysis?
Electrolysis is the process in which electricity is used to separate water molecules into hydrogen and oxygen gases. Electric current is passed through distilled water with some sort of electrolytes added to assist the current. The molecular bonds of the water are broken, and the hydrogen is collected at the cathode while the oxygen is collected at the anode. In a chemistry lab, a Hoffman apparatus is used to perform this experiment, but you can do it at home as long as you have a container to collect the hydrogen. Fill the large container 2/3 to 3/4 full of distilled water. Add electrolytes to the water. Do not use table salt, but most any other salt or other ion-producing molecules will work. Place the electrodes inside the collection bottles. Submerge the bottles in the water until they are filled and rest them against the side so they are at an angle with the bottoms above the water surface. Connect the power source to the electrodes. Bubbles will begin to form around the electrode
