Iron rusts through an electrochemical process that requires the presence of water. More acidic water, with a lower pH level, increases corrosion as more hydrogen ions consume electrons to create hydrogen gas instead of water. When iron is exposed to moist outdoor conditions, it begins to rust through this electrochemical reaction between iron, water, and oxygen.

• It is commonly known that when iron is left outdoors in moist conditions, it will begin to rust. • It is an electrochemical process, which requires the presence of water (Roberge 1).
• More acidic water increases corrosion. • The lower the pH is, more hydrogen ions will consume the electrons, creating hydrogen gas instead of water (Roberge 1).
