WebbThe proton formed in the oxidation reaction of hydrogen gas at the anode adheres to water molecules and forms provisional hydronium ions. Subsequently, one different proton from the same hydronium ion hops onto the other water molecule. In this mechanism, an ionic region forms specific hydrophilic clusters which swell in the presence of water.

Webb15 aug. 2024 · Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a positively charged cation. If a balanced atom gains one or more electrons, it will become a negatively charged anion. What is a cation?
