Which of the following will be formed when K4[Fe(CN)6] solution is added to FeCl3 solution?

Ferro-ferrocyanide Ferro-ferricyanide Ferri-ferrocyanide Ferri-ferricyanide

Ferri-ferrocyanide

When the solution containing ferric chloride is treated with potassium ferrocyanide solution a blue precipitate/colouration is obtained. The colour of the precipitate is Prussian blue. It is ferric ferro-cyanide. 4FeCl3​+3K4​[Fe(CN)6​] ⟶ Fe4​[Fe(CN)​6]3​+12KCl
