Corrosion and rubbing alcohol
vs.
corrosion and hydrogen peroxide

"Are brass, lead, iron, and aluminum more likely to corrode in solutions of rubbing alcohol or hydrogen peroxide?"
a. Definition-corrosion, rust, oxidation
Corrosion is the atmospheric oxidation of metals.
Rusting is essentially a process of oxidation in which iron combines with water and oxygen to form rust. Rust is the reddish-brown crust that forms on the surface of iron. Rust, a chemical compound, is a hydrated ferric oxide Fe2O3·nH2O, where n is usually 11/2. The chemical mechanism of rusting is not fully known, but is thought to involve oxidation of metallic iron to ferrous ion, (Fe++) and reaction of the ferrous ion with oxygen and water to form rust. This reaction is catalyzed by water, acids, and metals (e.g., copper and tin) below iron in the electromotive series. Because iron is so widely used, e.g., in building construction and in tools, its protection against rusting is important.......
