WebBasically, pennies are two layers: a copper outer layer that is very thin, and a thick zinc interior. If there are any scores or cuts in the penny exposing the zinc in the middle, it will react with HCl according to this reaction: Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g) So, as the zinc in the penny reacts with the hydrochloric acid, it ...
