Iron(III) Chloride 20 %
Iron(III) chloride 20% is a clear, yellow-brown solution used mainly in two fields: materialography and histology.
In materialography, iron(III) chloride is used to visualize the surface structure of metals, especially steel and iron. In this process, the ferric chloride reacts with the metal and changes its surface, making the microstructure of the metal visible under the microscope.
In histology, ferric chloride is used in Perl's reaction, a special staining method for visualizing iron deposits in tissue. In this reaction, trivalent iron (Fe3+) from iron(III) chloride is reduced to divalent iron (Fe2+) by reducing agents. The resulting Fe2+ then reacts with potassium ferricyanide (III) to form a blue colored Prussian Blue or Berlin Blue (Fe4[Fe(CN)6]3). This blue staining is visible under the microscope and allows the identification and localization of iron deposits in various tissue types.
