A reddish liquid with a strong aroma resembling that of hydrochloric acid is ferric chloride. Additionally, it can be found as a solid lump or anhydrous powder. Various businesses employ ferric chloride, also known as iron (III) chloride, as a flocking agent in the treatment of waste water and drinking water. When Anhydrous Ferric Chloride is diluted in water, ferric hydroxide forms and absorbs any contaminants that are suspended. A concentrated solution of ferric chloride with a minimum concentration of 40% by weight is typically employed. Additionally, ferric chloride is also employed as a crystalline solid in a small number of industrial applications.
The majority of metals corrode in aqueous ferric chloride solution due to its acidic nature. Most frequently, pickling liquors and chlorine gas are used to make Anhydrous Ferric Chloride. Additionally, several businesses employ ferric chloride, a byproduct of the production of titanium dioxide. Iron scraps are a common resource for manufacturing ferric chloride, which is a common process in sector. In this procedure, ferrous chloride is created by mixing ferric chloride with iron in a dissolving vessel. Ferrous chloride is subsequently oxidised into ferric chloride by interacting with chlorine gas. Additionally, the production of ferric chloride uses a number of additional feedstocks, including soft iron, mixed oxides, and ferric oxides.
