Ferrous choride - for Industry, agriculture

Water Treatment: Ferrous chloride is used as a flocculant in water treatment processes to remove suspended solids and phosphates, thus aiding in the purification of drinking water and the treatment of wastewater .

Production of Printed Circuit Boards (PCBs): It serves as an etching agent in the manufacturing of PCBs, where it removes excess copper .

Organic Synthesis: It acts as a reducing agent in various organic synthesis processes and as a Lewis acid in Friedel-Crafts reactions .

Iron Fertilizer: Ferrous chloride is used as an iron source in agriculture to prevent and correct iron deficiencies in plants, particularly in calcareous soils where iron bioavailability can be limited .

Biofortification: It can be used to enrich the iron content in crops, thereby improving their nutritional value and contributing to the fight against iron-deficiency anemia .

In addition to these applications, ferrous chloride is also utilized in the production of dyes, pigments, and as a reagent in chemical analyses. Its ability to form complexes makes it valuable in a range of industrial processes. However, due to its potential environmental impact, it is crucial to handle and dispose of ferrous chloride responsibly, adhering to safety guidelines and regulations .
