A little science help here ?! Thanks :)?
Hey guys!
I am doing a science investigative project on whether an acidic or alkaline medium would cause the rate of oxidation of iron nails to be the fastest. It seems that the solvent Coke causes the most damage to the iron nail in the form of pits (small, black holes.)
Could you tell me what type of acid coke contains and how that acid might promote the process of pitting in iron nails?
Thanks people :) I really appreciate your answers :P

Being carbonated, colas are acidic (carbonic acid is formed when carbon dioxide dissolves in water), and so can react violently with basic chemicals, such as baking soda. Many colas also contain phosphoric acid and/or citric acid, which further increases the acidity.
For further information, I suggest that you Google "acid in cola drinks."

Acid = Carbonic acid H2CO3
Acid + Metal = Metal Salt + Hydrogen
The metal salt in this case is iron carbonate (black when oxidized)
