What reaction occurs on the Impressed Current Anode ?
In Impressed Current Cathodic Protection, the reaction on the anode depends on the nature of the anode material. For inert anode such as Platinized, Titanium Oxide anode, oxidation of the chemical species in the environment occurs. For example, in sea water, the reaction is 2Cl- -2e ==> Cl2. For consumable anode, oxidation of the anode material itself constitutes the anodic reaction.
