Ferric Chloride (FeCl₃), CAS 7705-08-0, is also known as iron(III) chloride or ferric trichloride. It is an iron(III) salt used in water-treatment and metal-etching processes. For procurement review, confirm whether the offered material is anhydrous, hydrated, or a solution, together with the actual concentration where relevant, packaging, and applicable safety documentation.

Product Description
Product name: Ferric Chloride (FeCl₃)
CAS number: 7705-08-0
Molecular formula: FeCl₃
Molecular weight: 162.20 g/mol
EC number: 231-729-4
Other names: Ferric chloride; Iron(III) chloride; FeCl₃; Ferric trichloride
Chemical class: an iron(III) salt
Identity check: Ferric chloride and iron(III) chloride identify FeCl₃.
Technical context: water-treatment and metal-etching processes
Related water-treatment material: anionic polyacrylamide (APAM)
Ferric chloride is a coagulant. APAM is a polymer flocculant. Some water-treatment processes use both, but they are not interchangeable. Confirm suitability through process testing.
RFQ information: Before an RFQ, confirm whether the offered material is anhydrous, hydrated, or a solution, together with the actual concentration where relevant.
Offered form: Not specified; confirm the actual offered form.
Specification review: Confirm identity, relevant assay or impurity criteria, and suitability in the current technical dossier.
Safety: Follow the current SDS for the exact offered form and the receiving site’s controls.
Packaging and documents: Confirm packaging and applicable documentation for the actual offered product.
FAQ - Technical & Supply Chain
-
Q:
Are anhydrous Ferric Chloride and Ferric Chloride solution interchangeable?
A: No. Anhydrous FeCl₃, hydrated solids and aqueous Ferric Chloride solutions differ in formula basis, water content, concentration, density and dosing value. Specify the physical form, FeCl₃ or iron basis, solution concentration and free-acid basis. A CAS number alone does not define the commercial grade or delivered active content. -
Q:
Which specifications should be agreed for Ferric Chloride solution?
A: Agree FeCl₃ or total iron concentration and test method, ferrous iron, free hydrochloric acid, insoluble matter and relevant trace metals, plus density and crystallization behavior. Drinking-water, wastewater, etching and other uses may require different impurity limits. Review the batch COA and applicable product standard for the intended market. -
Q:
What should be specified for bulk Ferric Chloride delivery?
A: Ferric Chloride solution is highly corrosive. Agree tanker or IBC construction, lining, valve and gasket materials, venting, unloading connection, concentration and minimum handling temperature. Confirm previous-cargo and cleanliness records, net quantity, seals, current SDS and receiving-site containment before loading, and account for crystallization risk in cold conditions.
