Title: Iron Carbonate
Post by: kiko_milzo on January 06, 2011, 05:35:37 AM
Why Iron II Carbonate (FeCO3) does not Oxidize in air forming Iron III Carbonate(Fe2(CO3)3)?

It doesn't? Try to balance the reaction, perhaps something is missing.

i think thats due to its stabilbity as it forms the more stable FeIII oxide or hydroxide

(12) FeCl2 + (3) O2 →  (8 ) FeCl3 + (2) Fe2O3


On a sidenote, I made an interesting calculation that a solution of FeCl3 would oxidize the surface of silver metal.
(The reduction potentials are altered by the insolubility of AgCl)
