Original Post

The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example, in the electrolysis of brine to produce hydrogen and chlorine, the products are gaseous. These gaseous products bubble from the electrolyte and are collected.^[1]

Revised Post

The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The process requires that an electrolyte, an ionized solution or salt, completes a circuit between two electrodes. The cathode and the anode. Reduction always occurs at the cathode while oxidation always occurs at the anode. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes. For example, in the electrolysis of brine to produce hydrogen and chlorine, the products are gaseous. These gaseous products bubble from the electrolyte and are collected.(Disassociated hydrogen ions gain an electron at the cathode and pair off to become hydrogen gas, and chlorine ions are attracted to the anode where they lose an electron, become chlorine atoms, pair off, and become chlorine gas) ^[1]

Great Job! I really liked how thorough you are I your explanation. It is very easy to follow along, even for someone with a limited knowledge of chemistry. I feel that with these edits the article is much stronger and easier to understand. The only suggestion that I could make would be to include a mnemonic method for remembering that the oxidation occurs in the anode, while reduction occurs in the cathode. One example would be “AN OX and a RED CAT.” Then, obviously, you would have to explain how this is a good way of remembering.
