Description
Anhydrous ferric chloride 7705-08-0, often represented as FeCl3 (anhydrous), is a chemical compound of iron and chlorine. “Anhydrous” indicates that it is the dry, water-resistant ferric chloride. In contrast to hydrated ferric chloride, which contains water molecules within its crystal structure, anhydrous ferric chloride has all water molecules removed. Anhydrous Ferric Chloride exporter in India.
Key characteristics of anhydrous ferric chloride:
- Physical Properties: Anhydrous ferric chloride appears as a dark brownish-red solid in its pure form. It is typically in the shape of fine powder, crystals, or lumps, depending on how it is produced.
- Hygroscopic: Like hydrated ferric chloride, anhydrous ferric chloride is also hygroscopic, meaning it has a strong affinity for water and readily absorbs moisture from the atmosphere.
- Solubility: Anhydrous ferric chloride has limited solubility in water, but it can still dissolve to some extent, forming a reddish-brown solution.
- Chemical Properties: Anhydrous ferric chloride behaves as a strong Lewis acid and can accept electrons in chemical reactions. It reacts exothermically with water to form hydrochloric acid and ferric hydroxide.
Anhydrous ferric chloride shares many of the same applications as hydrated ferric chloride. Some of its common uses include:
- Water Treatment: Anhydrous ferric chloride is a coagulant in water and wastewater treatment for removing impurities.
- Etching: In the electronics industry, anhydrous ferric chloride is employed for PCB (printed circuit board) etching.
- Chemical Synthesis: It serves as a catalyst and reagent in various chemical reactions.
- Metal Surface Treatment: Anhydrous ferric chloride is used to clean and prepare metal surfaces before plating or coating.
