Question

What happens when ferric chloride is added to potassium ferrocyanide solution?

Answer 1

Here is your answer ⤵⤵⤵⤵

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.
