They are inorganic salts, they are man made- prussian blue was discovered over 200 years ago- the salts do not occur in nature- so are not normally considered to be minerals.
ferric hydroxide + citric acid ---> product A (ferric citrate)Product A + ammonia solution --> ammonium ferric citratecheck out for stoichiometric equation
how can i prepare ferric ammonium citrate redish crystals
because im black
Ferric Chloride = FeCl3Ammonium Hydroxide = NH4OHFerric (III) Chloride + Ammonium Hydroxide = Ferric (III) Hydroxide + Ammonium Chloride FeCl3 + 3NH4OH = Fe(OH)3 + 3NH4Cl

The true formula of ferric ferrocyanide is Fe4[Fe(CN)6]3.

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'.

Melanin will reduce ferricyanide to ferrocyanide producing a blue coloured compound in the presence of ferric salts (Schmorl's reaction)
Ferric Chloride = FeCl3Ammonium Hydroxide = NH4OHFerric (III) Chloride + Ammonium Hydroxide = Ferric (III) Hydroxide + Ammonium Chloride FeCl3 + 3NH4OH = Fe(OH)3 + 3NH4Cl
FeCl3 + 3NH4OH -> Fe(OH)3 + 3NH4Cl Ferric hydroxide
I think neutral ferric chloride is prepared by mixing iron(III) chloride with ammonium hydroxide.
