My textbook says lead reacts with acetic acid when there is enough oxygen to oxidize lead:
$$\ce{2 Pb + O2 + 4 CH3COOH -> 2 Pb(CH3COO)2 + 2 H2O}$$
So, I added lead into mixed solution of acetic acid and hydrogen peroxide. Immediately bubbles began to emit from the surface of the lead piece. After several days the lead chunk has been completely dissolved and pale yellow precipitate was formed. This is not what I expect considering the reaction above. Can the bubbling be attributed to the oxidation of lead by water?
I used rice vinegar as a source of acetic acid. It might have been contaminated with ions like $\ce{Cl-}$.
