Iron(III) chloride 14% is a solution of iron(III) chloride (FeCl3) in water, and the concentration of iron(III) chloride is 14%. Ferric chloride is a salt composed of iron and chlorine and is widely used in chemistry, especially in synthesis and analysis.

Iron(III) chloride finds application in various fields:

1. Precipitation reactions: It is often used as a precipitant for the isolation and purification of compounds.
2. Staining methods in histology: iron(III) chloride is used as a mordant in the staining of tissue sections to highlight certain structures such as elastic fibers.
3. Catalyst in organic chemistry: it is often used as a Lewis acid catalyst in Friedel-Crafts reactions in which acylation and alkylation reactions occur.
4. Water treatment: iron(III) chloride is used to flocculate and remove impurities from wastewater and drinking water.
5. Etchant: in the electronics industry, iron(III) chloride is used as an etchant to produce printed circuits by selectively removing copper from circuit boards.
