What is Prussian blue formula?
Fe4[Fe(CN)6]3
Prussian blue/Formula
What is Prussian blue reaction?
Prussian Blue or Perls’ reaction is used to demonstrate ferric iron and ferritin. The protein is split off by the hydrochloric acid, allowing the potassium ferrocyanide to combine with the ferric iron. This forms the ferric ferrocyanide or Prussian Blue.
What is the common formula of Turnbull’s blue and Prussian blue?
Calcium hexa cyano ferrate (II)
When Prussian blue is formed?
Prussian blue was first synthesized about 1704 by the reaction of salts of iron in the +2 oxidation state (ferrous salts) with potassium ferrocyanide; the initial product, an insoluble white compound called Berlin white, was then oxidized to the blue pigment.
How do you use Prussian blue?
Prussian blue is usually taken 3 times per day for at least 30 days. You may need to take several capsules at one time to get the correct dose. To make swallowing easier, you may open the Prussian blue capsules and sprinkle the medicine into a spoonful of liquid or bland food. Swallow right away without chewing.
How do you make a Prussian blue solution?
Procedure:
- Deparaffinize and hydrate sections to distilled water.
- Mix equal parts of hydrochloric acid and potassium ferrocyanide prepared immediately before use.
- Wash in distilled water, 3 changes.
- Counterstain with nuclear fast red for 5 minutes.
- Rinse twice in distilled water.

What are Prussian blue analogs?
Prussian blue analogues (PBA) are promising as cathode material for a number of different battery types because of their excellent redox properties and relatively high standard potential [1–7]. The cage-like structure exhibits wide channels, allowing for insertion of a wide range of intercalation ions.
What pigment is in Prussian blue?
Prussian blue, any of several deep-blue pigments that are composed of complex iron cyanides and hence called iron blues. The most common of these pigments are Prussian, Chinese, Milori, and toning blue.
What can I use instead of Prussian blue?
Winsor Blue
Winsor Blue was created as a stable and lightfast version to replace Prussian blue.
What is the empirical formula for Prussian blue?
The pigment Prussian blue consists of iron cations, cyanide anions, and water. The empirical formula—minus the water of crystallization—is Fe7(CN)18.
How is Fe ( CN ) 6 anion in Prussian blue?
As shown in the two left-hand drawings, the Fe (CN) 6 anion in Prussian blue is octahedral. The right-hand drawing shows its unit cell, which has a cubic lattice structure. In addition to having as many as 16 molecules of water per formula unit, the compound usually contains inorganic impurities, which can affect its color.
What is the active ingredient in Prussian blue?
Ferric hexacyanoferrate also known as insoluble Prussian blue (PB), is the active pharmaceutical ingredient (API) of Radiogardase which is the first approved drug product (DP) for treatment of thallium and radiocesium poisoning.
What kind of metal is Prussian blue made of?
Prussian blue is designated ferric ferrocyanide (Fe 4 [Fe (CN) 6] 3 .xH 2 O), but it is not very toxic as the cyanide ions are firmly held by the iron ions. Indeed, in its pure form it has medical uses as a sequestering agent for various heavy metals such as thallium and caesium-137.
