WebJay just turned the reduction potential of the aluminum (-1.66) into an oxidation potential (+1.66) by changing the sign of the potential. And it's this oxidation potential of aluminum we can add to the reduction potential of iodine to get Ecell. But it's obviously the same math as before using only the reduction potentials. WebMar 16, 2024 · The science behind galvanic corrosion Corrosion potential and the galvanic series. When a metal corrodes in an electrolyte, atoms from the metal separate into ions and electrons (e-), with the ions dissolving into the electrolyte. For example, for iron (Fe) the reaction is: Fe → Fe 2+ + 2e −. This is called an anodic reaction and Fe 2+ …
WebApr 13, 2024 · Electrochemical depolymerization of synthetic polymers is a promising approach for plastics upcycling as it could utilize renewable electricity to create an external potential, shifting the system out of equilibrium. 3 Thus, an electrochemically-driven process could overcome the thermodynamic constraints that the endothermicity of the C−C ...
