WebIf the anion is a halide, the equivalent halogen will form at the anode; otherwise, oxygen gas will form. The reactivity series can be used to predict which materials will be inert; if the electrode material is less reactive than elements that make up the salt, the electrode will be unreactive during electrolysis.
