Ferric chloride, in solution form, is a light brown aqueous liquid with a faint odor reminiscent of hydrochloric acid. Ferric chloride (FeCl3) is a versatile and widely
used iron salt, primarily employed for its effective coagulation properties.
It is extensively utilized in the treatment of sewage and industrial waste to purify water.
Additionally, ferric chloride serves as an etching agent in the production of printed circuit boards and plays a significant role in the manufacturing of various other chemicals. Its ability to coagulate and precipitate impurities makes it an essential component in water treatment processes.
