iron is not an acid or an alkali, as it is not an oxideiron oxide however is an alkali


Iron Oxide + Sulphuric Acid = Iron Sulphate + Water


There are different types of iron oxide. Iron (III) oxide is used in the following equation: acid + metal oxide -> metal salt + water hydrochloric acid + iron oxide -> iron chloride + water 6HCl + Fe2O3 -> 2FeCl3 + 3H2O


Iron oxide is a basic oxide. So yes, a base.


iron with concentrated nitric acid no reaction occurs becase of the iron passivity which is due to the oxidizing property of the acid were a layer of the metal oxide is formed which is complete and non porous so it protects the metal from further reaction


The reaction isȘFeO + H2SO4 = FeSO4 + H2O


No. A salt is a product of a neutralization reaction between an acid and a base, or an acid and a metal, or an acid and a metal carbonate. example: HCl+NaOH--->H2O+NaCl copper oxide is created by adding oxygen into copper and heating. Not a neutralization reaction, therefore not a salt.


The chemical reaction is:ZnO + 2 HNO3 = Zn(NO3)2 + H2Adding more HNO3 has no effect.


Iron Oxide is Fe[2]O[3] and Nitric acid is HNO[3]


No it is not. A neutralisation reaction involves an acid and a base reacting to produce water and a salt.


Iron Oxide+Hydrofluoric Acid --> Iron Fluoride + water For Iron II oxide: FeO+ 2HF --> FeF2 + H2O For iron III oxide Fe2O3 + 6 HF --> 2 FeF3+ 3 H2O Iron II,III oxide Fe3O4 + 8HF --> FeF2 + 2FeF3+ 4 H2O



that would be a acid-metal oxide reaction see related link for more info


The chemical reaction is:CuO + H2SO4 = CuSO4 + H2O


Iron 3 oxide is Fe2O3 Carbonic acid is combination between water and carbon dioxide = H2CO3


Copper(II) Oxide: CuO reaction with Nitric Acid: CuO + 2 HNO3 => Cu(NO3)2 + H2O Copper(I) Oxide: Cu2O reaction with Ntric Acid: Cu2O + 2HNO3 => CuNO3 + H2O


A reaction between an acid and a metal oxide to form a salt and water as the only products.

Nitric acid is oxidizing acid. When it reacts with iron it forms a protective layer of iron oxide over it. So it does not react further.


Iron II Oxide FeO + H2SO4 = FeSO4 + H2O Iron III Oxide Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O


Acid does not remove rust, however the use of phosphoric acid on rust converts the iron oxide to iron phosphate, which in turn can be painted without the fear of rust forming. The iron phosphate surface will not deteriorate the metal like iron oxide does.


there are no changes because the metal has already reacted with oxygen to form a metal oxide reaction is done.



Citric acid can be extracted from the juice of citrus fruits by adding calcium oxide (lime). The citric acid can be recovered from its calcium salt by adding sulfuric acid.
