properties 
  
The yellowish pieces of the hexahydrate, which smell slightly of hydrochloric acid, are highly hygroscopic and attract water in the air, so that they dissolve into a dark brown liquid. But they also dissolve in acetone, ethyl alcohol and diethyl ether.
   



The iron (III) chloride hexahydrate is obtained in this form for etching


If you add potassium hexacyanoferrate (II) to an iron (III) chloride solution, a deep blue precipitate of the pigment Berlin blue is produced. Anhydrous ferric chloride forms dark, green leaves when viewed from above, which melt at +307.6 ° C and at the same time partially sublime.
   
  
Manufacturing 
  
Brown, anhydrous iron chloride is obtained in the laboratory from the reaction of iron wool and chlorine. The iron chloride containing water of crystallization can also be produced by dissolving iron powder in hydrochloric acid and then introducing chlorine, the iron (II) chloride initially formed being FeCl converts into iron (III) chloride, which can be obtained by evaporating the solution. For technical production, chlorine is passed over scrap iron at around 650 ° C.
   
  
use 
  
Iron (III) chloride is required as a chemical reagent in the laboratory. It is used as an oxidizing agent and pickling agent in textile printing. In water treatment it is used to precipitate and flocculate impurities, in medicine as a hemostatic agent (astringent), in copper gravure to etch metals and in electronics to etch circuit boards. The chemical industry needs ferric chloride in the production of dyes such as aniline black.
