Solution:

The chemical formula of Prussian blue is $Fe _{4}\left[ Fe ( CN )_{6}\right]_{3}$. $Fe ^{3+}$ reacts with sodium ferrocyanide to give ferriferrocyanide (Prussian blue) as follows

$4 Fe ^{3+}+3 Na _{4}\left[ Fe ( CN )_{6}\right] \rightarrow Fe _{4}\left[ Fe ( CN )_{6}\right]_{3}+12 Na ^{+}$
