    What is it about the atomic makeup of carbon electrodes that makes them neutral in electrolysis?

    Most metals easily dissolve in ionic form (unless they are noble metals - but these are expensive). Carbon can be oxidized to carbon dioxide, but this is a slow process, besides, product is a gas, which will easily leave the solution.
