Iron(III) carbonate or ferric carbonate.
Iron III carbonate, Fe2(CO3)3 ===================== From Pisgahchemist: You might think that Fe3+ and CO3^2- ions might combine to make insoluble Fe2(CO3)3, but you would be wrong. Fe2(CO3)3 does not exist. It turns out that solutions of metal ions with higher oxidation states tend to be more acidic. Iron in the +3 oxidation state is too acidic to form the carbonate. You get CO2 gas instead. Therefore, you can have FeCO3, which is iron(II) carbonate, but there can be no no Fe2(CO3)3.
Fe2 (SO4)3
Carbonates and bicarbonates of metals. For example: Na2CO3, CuCO3, KHCO3, Ca(HCO3)2, Fe2(CO3)3, CoCO3, etc.
This compound is iron(III) hydrogenphosphate.
Balancing equation of FeCl2 and Na2CO3 yield 2NaCl and FeCO3
Fe+3 CO3-2

The formula of the compound is Fe2(CO3)3 i.e. ferric carbonate
Fe2(Co3)3 --> Fe2O3 (s) + 3CO2 (g)
if iron has an oxidation state of +2 K2(CO3) + FeBr2 ---> KBr + FeCO3 if iron has an oxidation state of +3 3K2(CO3) + 2FeBr3 ----> 6KBr + Fe2(CO3)3
Fe2 (SO4)3
I'm sure that you cannot have the formation of Iron (iii) carbonate due to it's strong acidic nature, however when we have iron(iii)hexa-aqua ions and add some carbonate, which acts as a base, we form iron(II) carbonate. FeCO3. This is just what I have learnt feel free to challenge or correct me anyone.
The symbol "CO3" stands for the chemical compound Carbon Trioxide. C stands for Carbon O stands for oxygen 3 represents how much oxygen there is (if the 3 was in between the "C" and "O" then it would represent the amount of carbon)
Fe2(SO4)3 is Iron (III) Sulphate.
Carbonates and bicarbonates of metals. For example: Na2CO3, CuCO3, KHCO3, Ca(HCO3)2, Fe2(CO3)3, CoCO3, etc.
the corrosion elements are CO2 and H2O. but rust is ferric oxide. so simple equation is, 2Fe + 3O2 = Fe2O3 but oxygen directly does not react with iron actual mechanism is, CO2 + H2O = H2CO3 2Fe + H2CO3 = Fe(HCO3)2 + H2 2H2 + O2 = 2H2O 2Fe(HCO3)2 = Fe2(CO3)3 + CO2 + 2H2O Fe2(CO3)3 = Fe2O3 + 3CO2
Fe2(CO3)3(s). Carbonate compounds are notoriously insoluble, whereas K+ and NO3- are almost always soluble with everything. That is why a carbonate precipitate forms.
