hodic processes - Corrosion Doctors

When hydrogen ions are reduced to their atomic form they often coine, as shown earlier, to produce hydrogen gas through reaction with electrons at a hodic surface. This reduction of hydrogen ions at a hodic surface will disturb the balance between the acidic hydrogen (H + ) ions and the alkaline hydroxyl ( OH - ) ions and make the solution less acidic or more alkaline or basic in this
