WebAcid can dissolve the rust (Fe 2 O 3). However, the acid will also oxidize the metal further, forming more rust, and dissolving that rust. In the simplest case, lets imagine hydrochloric acid and iron (HCl and Fe). When HCl encounters iron, whether it is oxidized iron (Fe 2 O 3) or metallic iron (Fe), it wants to form iron chloride (FeCl 2 or ...

WebMar 10, 2024 · Hydrochloric acid (which is also called muriatic acid in its diluted form), as well as phosphoric acid and sulfuric acid may be used in rust removal formulas using strong acids. These are mineral acids, and they are highly corrosive, especially in concentrated forms. Strong alkalis work in a similar way, but on the opposite end of the pH spectrum. WebApr 30, 2024 · Phosphoric acid is stronger than acetic acid, and so is ionized to a greater extent. Acetic acid is stronger than carbonic acid, and so on. The Acid Ionization Constant, K a The ionization for a general weak acid, HA, can be written as follows: HA(aq) → H + (aq) + A − (aq) Because the acid is weak, an equilibrium expression can be written.
