Now according to Wikipedia, the Turnbull blue and Prussian blue are the same compound, ie, ferriferrocyanide $\left(\ce{Fe4[Fe(CN)6]3} \right)$. But the book says that Turnbull blue is ferroferricyanide $\left(\ce{Fe3[Fe(CN)6]2}\right)$ which kinda makes sense because we are adding ferricyanide to ferrous solution.. As a result, knowing that CN− is cyanide, the inner sphere iron is Fe3+, since 6 × −1 +3 = −3 for the total anionic charge. Well, hopefully you can see that there are two different iron atoms here. Otherwise, it wouldn't make sense to write the two "Fe" atoms separately like this. If you really meant "Fe"_4 ["Fe" ("CN")_6]_3, Prussian.

The Iron One-Pot Reaction. Complex-formation and oxidation/reduction chemsitry of iron. The following solutions are added to a beaker containing 0.10M FeSO 4 solution. Solution: Chemical Equation: Observations: Sodium Citrate. Fe 2+ (aq) + C 6 H 5 O 7 3- (aq) <=> Fe (C 6 H 5 O 7) - (aq) A light yellow complex forms.. Fe(CN) 6 3H 2 O] and potassium ferricyanide [K 3 Fe(CN) 6] complexes are used in this experiment. The cyano group in each complex has a charge of -1 and potassium has a charge of +1. Thus, the complex ferrocyanide, Fe(CN) 6 4-, contains iron in the +2 oxidation state while the complex ferricyanide, Fe(CN) 6 3-, contains iron in the +3.
