ferrous ammonium sulphate + potassium ferrocyanide ->
or
FeSO4(NH4)2SO4 x 6H2O + K4[Fe(CN)6] ->
or
FeSO4(NH4)2SO4 x 6H2O + K4[Fe(CN)6] ->
There is not really a reaction because iron is in both cases Fe-II.
If one of it is Fe-III then a blue colour of prussian blue will be formed. Fe3[Fe(CN)6]2 Iron-II-hexacyanoferrate-III or Fe4[Fe(CN)6]3 Iron-III-hexacyanoferrate-II
So need either K3[Fe(CN)6] or NH4Fe(SO4)2
