What is the reaction with potassium ferrocyanide?
Potassium ferrocyanide is commonly used as a reagent in laboratory settings. One common reaction is the formation of Prussian blue when potassium ferrocyanide reacts with iron(III) salts. This reaction results in the formation of a dark blue precipitate, known as Prussian blue.
How can I make Prussian blue?
To make Prussian blue, mix together iron(III) chloride, potassium ferrocyanide, and water. Heat the mixture and allow it to cool to form the deep blue pigment known as Prussian blue.
What test would you use to confirm that you have a solution of FeCl3?
You can use a precipitation test by adding NaOH solution to identify FeCl3, which forms a red-brown precipitate of iron hydroxide. Another test involves adding potassium ferrocyanide, which forms a deep blue precipitate of ferric ferrocyanide. Both of these confirm the presence of FeCl3.
What is the formula of the colored precipitate obtained in the nitro prusside test?
Sodium nitroprusside is used for detection of sulphur in organic compounds. If sulphur is present in the organic compound, sodium fusion will convert it into sodium sulphide. Sulphide ions are readily identified using sodium nitroprusside. Na + S = Na2S Na2s + Na2[Fe(CN)5NO] = Na4[Fe(CN)5NOS] Sodium nitroprusside violet colour Submitted by Dr Arun Trikha on July 22nd 2012 .
What colour does Ferric chloride burn?
Ferric chloride burns with a blue/green flame.
How do you get prussian blue precipitate?
Put together a ferric ions containing solution and dissolved potassium ferrocyanide Fe3+ + K+ + [FeII(CN)6]4- --> KFeIII[FeII(CN)6] , colloidal precipitate of potassium ferric ferrocyanide which is 'Prussian blue'.
Are ferric ferrocyanide and ferric ammonium ferrocyanide minerals?
No, ferric ferrocyanide and ferric ammonium ferrocyanide are not minerals. They are chemical compounds used as pigments in various applications such as inks, paints, and dyes. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure.
What is the reaction with potassium ferrocyanide?

Why alkaline solution containing ferrous ions is boiled during detection of nitrogen?
To convert ferrous ions to ferric as Fe2(SO4)3 .which then react with sodium ferrocyanide to give prussian blue colour.
How can I make Prussian blue?
To make Prussian blue, mix together iron(III) chloride, potassium ferrocyanide, and water. Heat the mixture and allow it to cool to form the deep blue pigment known as Prussian blue.
When potassium ferro cyanide and ferric ammonium combine it turns Prussian blue?
Probably, depending on the thermodynamics, I would assume that the ammonia goes into solution as an ion as does the potassium. Looking at the Wikipedia article, the formula for Ferric Hexacyanoferrate is Fe7(CN)18(H2O)x. Again. It depends on the thermodynamics of each solution. If the Energy to create the prussian blue is greater than the energy required to destruct either iron cyanide compound, then there would be no reaction taking place without a catalyst (or external energy source). Best thing for you to do is either look up the data in a thermo program like HSC or mix the two solutions veeeerrry carreefully using correct safety lab equipment. Hydrogen Cyanide is a pretty angry chemical when the pH isn't at a good alkaline level. Best of luck to ya
What is Perls Prussian blue stain?
a stain for ferric iron as in hemosiderins, using potassium ferrocyanide in acetic acid or dilute hydrochloric acid followed by a red counterstain such as safranin O or neutral red; various hemosiderins and most mineral irons give a blue-green reaction, while nuclei stain red.
