Does iron react with nitric acid?

Answer 1

based on the reactivity series, calcium ranks higher in reactivity than iron(iii), hence the Ca will displace the iron ion from the solution causing a precipitate to form. The equation will read

Ca (s) + Fe(NO3)^3= Ca(NO3)^2 + Fe (s)

Answer 2

No, no reaction occurs. That is because iron is less reactive that calcium, and in order for iron to replace calcium in calcium nitrate and make a reaction, it needs to be more reactive to displace it.

A stronger metal than iron, for example, sodium, WOULD displace calcium, therefore making a reaction. You can know wether a metal is more reactive than another by the reactivity series (you can get it from anywhere on the internet).

Hope that helped :)

Answer 3

I would assume that is would under the right circumstances. I would say this reaction isn't likely to happen because the electronegativity of iron is higher than that of calcium; oxygen is more attracted to calcium because of the greater electronegativity difference.

Answer 4

No, iron does not react with calcium nitrate. This is because iron is less reactive than calcium and it cannot replace the calcium in the reaction.

Answer 5

YES IT DOES
