Question

What happens when ferric chloride is added to sodium ferrocyanide

Answer 1

Answer:

If we add ferric chloride over potassium ferrocyanide,

Explanation:

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 a small quantity of ferric chloride, not all potassium is displaced.
