11. Liquor Ferri Chloridl. Solution of Ferric Chloride

11. Liquor Ferri Chloridl - Solution of Ferric Chloride. An aqueous solution of Ferric Chloride (Fe2Cl6=323.98), containing about 37.8 per cent. of the Anhydrous Salt, or corresponding to about 13 per cent. of Metallic Iron.

Source

Dissolve Iron Wire, 15.8, in Hydrochloric Acid, 870, and water to 1000. Fe+2HCl=FeCl2+H2. Nitric Acid is also added, and thus the Ferrous is converted into Ferric Chloride. 6FeCl2+6HCl+2Hno3 =3Fe2Cl6+4H2O+2NO.
