sulfuric acid
Hydrochloric Acid
No, water is neutral. It has no acid in it whatsoever.
The citric acid reacts with the oxidation on copper.
Yes there is an acid in the pennies that kills the toxins found in the salvia.
There is acid called ACETIC ACID it combines with the copper to form a copper acetate(the green coating on the pennies)!!!!!!!!!!!!!!!!!! coiol huh

Malic acid can be used to clean a variety of metals because it is gentle. A solution of malic acid will clean pennies. It is also suitable for cleaning stainless and other carbon- steel as it will not stress or crack the alloy. This makes it very handy for cleaning the heating filament in kettles, too (and you can trust me on this, because I've actually done it several times).
Lemon juice works best for cleaning pennies because the acid helps dissolve the tarnish. Dish soap can also clean pennies by removing dirt and oils, but it may not be as effective at removing tarnish. Water alone may not be sufficient for thorough cleaning.
A mixture of vinegar and salt or a commercial acid-based cleaning solution can effectively clean pennies. The acid helps to dissolve the tarnish and dirt on the surface of the pennies, revealing the shiny copper underneath.
The acidic nature of citrus fruits such as lemon and lime juice helps to dissolve the oxidation on pennies, which makes them appear cleaner. The citric acid in these juices breaks down the tarnish and restores the shine on the surface of the pennies.
The acid and vinegar in it. By the way, it's does, not do.
It corrodes it because it includes oxygen and hydrogen.
