The Subatomic Assembly of Hydrogen My first exercise in hydrogen production was to drop a 9-volt battery into a cup of water. I had managed to assemble pure hydrogen gas out of subatomic particles. The protons came from the water itself, which always has a bunch of them running around loose (naked protons are also called hydrogen ions). The electrons came from the battery. When I injected the electrons into the water, they latched onto the protons to form a few small bubbles of hydrogen gas. From there I added salt to the water to increase its conductivity, thereby increasing the flow of current and the number of electrons available to pair up with all those wild protons. As current flows from the 9-volt battery through a cup of water, bubbles of hydrogen form on the negative electrode while oxygen accumulates on the positive one. To determine which electrode produces which gas, hold a match near the surface of the water. The hydrogen gas bubbling off the negative electrode crackles and flashes as it reacts with oxygen in the air, forming water. Although it’s flammable, you won’t generate enough with a 9-volt battery to make it dangerous. Adapted from an article by Theodore Gray in Popular Science, December 2003, p. 146. 52.

The use of inappropriate language or content may result in a mark of zero being awarded. 5. Upon completion of the examination, return all examination materials to the supervising invigilator.
