Balancing a cyanotype (time sensitive)

Post by TheVybes »

Hey folks. Need some pretty urgent help.
In my chemistry class, we made blueprints. We mixed Iron (iii) ammonium citrate solution and potassium hexacyanoferrate (iii) together and, when exposed to UV light, yielded Prussian blue, plus some potassium and water. Part of the lab was to balance the equation. I've been having so much trouble I'd figured I'd come on here.
Here's what I have so far:
C6H10FeNO8 + C6N6FeK3 -> C18Fe7N18 + K3 + H2O

I've gotten this down so far, but I really have no idea how to balance this. Help is greatly appreciated!!

The basic reaction is Fe 3+ + [Fe(CN)6] 4-

You get Fe4[Fe(CN)6]3

The other ions are spectator ions. By the way there is no potassium developed. Impossible in aqueaeous solution.

Iron II is build by photochemical reduction under help of citric acid.

See in this paper below
