Overview
Potassium ferricyanide is also one of two compounds present in ferroxyl indicator solution (along with phenolphthalein) which turns blue (Prussian blue) in the presence of Fe2+ ions, and which can therefore be used to detect metal oxidation that will lead to rust. It is possible to calculate the number of moles of Fe2+ ions by using a colorimeter, because of the very intense color of Prussian blue Fe4[Fe(CN)6]3.
SAFETY :
Potassium ferricyanide has very low toxicity, its main hazard being that it is a mild irritant to the eyes and skin. However, under very strongly acidic conditions, highly toxic hydrogen cyanide gas is evolved, according to the equation:
6 H+ + [Fe(CN)6]3− → 6 HCN + Fe3+[9]
The reaction with hydrochloric acid is as follows:
6 HCl + K3[Fe(CN)6] → 6 HCN + FeCl3 + 3 KCl

Applications
- Potassium ferricyanide (Prussian Red) is an orange solid, It is mainly used as a pigment for staining or in photography, but also in analytical chemistry for its oxidizing properties.Potassium ferricyanide(III) is a potassium salt widely employed as an external indicator in potassium dichromate titrations.
- A sensor containing potassium ferricyanide assisted enzyme electrode for estimating maltose and glucose in samples has been reported. Addition of potassium ferricyanide in the catholyte can improve the generation of power in microbial fuel cells (MFCs).
- Potassium ferricyanide was used with ferric ammonium citrate to sensitize paper for the cyanotype process and mixed with hypo to make Farmer’s reducer which was used to reduce the density of silver-based images.
- This compound found various applications such as producing blueprints, photography, wood staining, wool dyeing, calico printing, etching liquid (Mercer's liquor), tempering iron and steel, electroplating, mild oxidizing agent in organic synthesis, and analytical chemistry.
- It is used in many amperometric biosensors as an electron transfer agent replacing an enzyme's natural electron transfer agent with the enzyme glucose oxidase. It is a major component of Murakami's etchant for cemented carbides.

Characteristics and notes
Detecting free Iron : Spray the surface with a solution of potassium ferricyanide. If free iron is present, a blue color will appear. This test is extremely sensitive and often gives false positive results, that is, it gives an indication of iron being present when it really is not. The ferroxyl solution must be made fresh each day by addition with Nitric acid. The ferroxyl tests are described in ASTM A380.
Ferroxyl indicator is a solution containing potassium hexacyanoferrate(III) and phenolphthalein. It turns blue in the presence of Fe2+ ions, pink in the presence of hydroxide ions, it can be used to detect metal oxidation. It is often used to detect rusting in various situations.
It can be prepared by dissolving 10g sodium chloride and 1g potassium hexacyanoferrate(III) in distilled water, adding 10 cm3 phenolphthalein indicator, then making up to 500 cm3 with distilled water.
