Ferrous Iron Salts (FeCl₂/FeSO₄) -- Industrial Applications in Water & Wastewater

In this article, Loc Thien will explore the chemical ferrous chloride (FeCl2) and its uses in industry and manufacturing. The article covers topics such as chemical properties, handling, storage, and important precautions for ferrous chloride in the laboratory.

What Is Ferrous Chloride (FeCl2)?

It is a substance with a high melting point and appears white or pale green in powder form as a solid.

FeCl2 Chemical

Furthermore, FeCl2 has sin hygroscopic properties and dissolves easily in water.

Chemical Properties of Ferrous Chloride

• Acidity: Ferrous chloride has mild acidity, creating an acidic environment by releasing iron ions and chlorine ions in water.


• Reaction with air: FeCl2 oxidizes very easily on contact with air, producing FeCl3


• Solubility: FeCl2 dissolves easily in water, and the resulting solution is green


• Reducing agent: In many reduction reactions, FeCl2 shows its reducing properties by converting iron (II) ions into iron (III) ions


• FeCl2 also has magnetic properties and interacts sinly with magnetic fields

Industrial Uses of FeCl2

• Ink production with Ferrous Chloride: thanks to its oxidizing properties, this chemical not only produces deep black ink but is also applied in FeCl2 in the textile industry to create fade-resistant, attractive colors for fabric.


• Metallurgy: at some factories, FeCl2 is used to remove stains from metal surfaces


• Water treatment: thanks to its ability to precipitate many heavy metals, ferrous chloride in water treatment is widely used for sedimentation, water purification, and ensuring the safety of wastewater discharged into the environment.


• Ferrous chloride in battery production: FeCl2 is used as an electrolyte to form a metal oxide layer on the surface of electrodes during battery manufacturing.


• Other applications: FeCl2 has many other applications in dye production, chemical analysis, and textile dyeing chemicals, helping improve production efficiency and product quality.

How to Use and Store Ferrous Chloride

Using FeCl2:

• When working with FeCl2, wear protective clothing, gloves, and goggles to protect skin and eyes.


• Open all doors to create a well-ventilated working environment to avoid inhaling chlorine vapor from the compound.


• Minimize exposure of this chemical to air and water so that it does not degrade or oxidize


• When using ferrous chloride in the laboratory, it should be done under the supervision of an experienced person.

Storing FeCl2:

• Store in an air-free environment to prevent the product from oxidizing. Use anti-oxidation containers or oxygen-absorbing bags to hold the chemical.


• Iron (II) Chloride is highly hygroscopic, so it should be kept in a location with minimal humidity.


• Keep FeCl2 in a cool place and avoid high temperatures to prevent the generation of toxic gases.


• Label containers fully, including the chemical name, production date, and expiration date of the FeCl2 container.


• Keep this chemical out of reach of children or people without experience handling it.

Precautions When Using Ferrous Chloride in the Laboratory

Using Ferrous Chloride in the Laboratory

Ensure safety: Follow laboratory safety rules when working with iron (II) chloride. To ensure safety, wear protective equipment such as safety goggles, gloves, and a lab coat to avoid direct contact with the product.

Limit air exposure: FeCl2 can absorb moisture from the air, so be sure to seal the product tightly when not in use to avoid unwanted oxidation.

Check solubility: Before use, check the solubility of FeCl2 in solution to control batch quality of the product before use.

Store properly: To store this chemical, place it in sealed containers and store in a dry, well-ventilated place to avoid the effects of sunlight and prevent oxidation.
