Ferric Chloride is also called Iron(III) Chloride. It is soluble in water and alcohol and is non-combustible.

When dissolved in water, ferric chloride undergoes hydrolysis and gives off heat in an exothermic reaction. The resulting brown, acidic, and corrosive solution is used as a flocculant in sewage treatment and drinking water production, and as an etchant for copper-based metals in printed circuit boards. If you are looking for an etchant, see our Ferric Chloride 40% Etchant Solution.

Used in our Patina formula No. 4 for Florentine Brown.
