2. • 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).

3. • 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).
