What happens when ferric chloride is added to potassium ferrocyanide

If we add ferric chloride over potassium ferrocyanide, it forms a white precipitate that will become blue. The reaction is : FeCl3 + K4[Fe(CN)6] → KFe[Fe(CN)6] + 3 KCl and this is normal, because being small quantity of ferric chloride, not all potassium is displaced.

Hope it's help you... : ))

Answer:

Dark blue precipitate called Prussian blue is formed

Explanation:

Ferric chloride on reaction with potassium ferrocyanide gives potassium diiron(III) hexacyanoferrate which is dark blue precipitate called Prussian blue and potassium chloride.

The reaction is shown below:

FeCl_3+K_4[Fe(CN)_6]\rightarrow KFe[Fe(CN)_6]+3KCl

This test is a qualitative method for the detection of the Fe^{3+} ions.
