Description
When dissolved in water, iron(III) 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. Anhydrous iron(III) chloride is a fairly strong Lewis acid, and it is used as a catalyst in organic synthesis.
Keywords：Chloride
USES
Mainly used for the engraving etching of electronic circuit board or purify drink water and treat waste water. It is also used to make other iron salts, oxidant, catalyst, mordant and ink. In addition, it is used in construction field.
