K3Fe(CN)6 + Fe3+ --->

i am doing a science lab and am having trouble finding information. i know that this reaction gives a brown solution, but i am not sure what to write as the products. Since there is not precipitate that forms (i think) , do all the the ions remain uncombined in the solution?
my main question is the products to this reaction! thanks! (:

Hi ruby,

I think that Fe^3+ is a typo, the correct ion is Fe^2+ since Fe^3+ does not react with K3[Fe(CN)6].

So I assume Fe^2+.

Molecular equation:

3 FeSO4 + 2 K3[Fe(CN)6] ---> Fe3[Fe(CN)6]2 + 3 K2SO4

K3[Fe (CN)6] is a red blood salt.

Ionic net equation:

3 Fe^2 + + 2 [Fe(CN)6]^3 - ---> Fe3[Fe(CN)6]2 is a very dark blue precipitate

Spectator ions: K^+ and (SO4)^2-

Answers:

1) K3Fe(CN)6 doesn't react with Fe^3+ so, all the the ions remain uncombined in the solution.

2) If you assume Fe^2+ then see above.
