Ferric Chloride, also known as Iron (III) Chloride with the chemical formula FeCl3, is a significant industrial compound with a variety of uses. It is recognized for its ability to act as a catalyst, coagulant, and etchant among other applications. Here are some of the key uses and properties of Ferric Chloride:
Water and Wastewater Treatment: Ferric Chloride is extensively used in the treatment of water and wastewater due to its effectiveness in coagulation and flocculation processes. It helps in the removal of suspended solids and impurities from water, thus playing a crucial role in purifying water supplies .
Production of Printed Circuit Boards (PCBs): In the electronics industry, Ferric Chloride is utilized in the etching process of PCBs, which are essential components in most electronic devices .
Metal Etching: It serves as a mild oxidizing agent and is used for etching metals such as copper, stainless steel, and aluminum. This application is vital in the production of various hardware items, electronic devices, and decorative items .
Dye and Pigment Manufacturing: Ferric Chloride is used in the production of certain dyes and pigments, contributing to the coloration process in textiles and other industries .
Laboratory Applications: In laboratories, it is commonly used as a Lewis acid to catalyze reactions such as Friedel-Crafts reactions and chlorination of aromatic compounds .
Pharmaceutical Industry: It is also used as a reagent in the synthesis of certain pharmaceuticals .
Ferric Chloride Test: It is known for its use in a traditional colorimetric test for phenols, where the presence of phenol or enol groups in a sample can be identified by a color change upon the addition of Ferric Chloride solution .
Physically, Ferric Chloride appears as a dark-colored crystal and is corrosive to most metals and tissues. It is non-combustible and has a molecular weight of approximately 162.204 g/mol (anhydrous). The anhydrous form is deliquescent and can absorb moisture from the air, partially hydrolyzing and releasing hydrogen chloride .
