Formulated with a molecular formula of Cl3Fe and a molecular weight of 162.20, this dense, orange to brown-black liquid solution is utilized heavily in industrial water management and specialized manufacturing. The concentration is maintained precisely at 40% to ensure consistency and reliable dosing in high-volume applications. This chemical solution exhibits high density and is heavier than water, ensuring proper mixing and settling behaviors when introduced into aqueous treatment processes.\u003c\/p\u003e\u003cp\u003eBeyond industrial water treatment, Ferric Chloride 40% is highly valued as a high-performance etching agent in the electronics industry for engraving printed circuit boards (PCBs) and other metallic surfaces. Its corrosive nature makes it highly effective at dissolving unwanted copper from clad laminates, leaving behind clean, precise conductive pathways. We offer this solution in various sizes, which can be viewed in our \u003ca href=\"\/collections\/water-treatment\"\u003ewater treatment chemicals collection\u003c\/a\u003e. This product is supplied with a commitment to quality and traceability, ensuring that your manufacturing facility or municipal treatment operation receives a consistent and compliant product. We provide both small-scale packaging and bulk volumes to accommodate various operational demands.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eThis Ferric Chloride solution is formulated specifically at a 40% concentration, which is the industry standard for stable liquid handling and efficient transport. Choosing a pre-diluted 40% solution instead of anhydrous solid Ferric Chloride eliminates the safety hazards and exothermic dissolution risks associated with mixing dry ferric salts with water on-site. The 40% concentration is carefully balanced to remain fully soluble under typical operating temperatures, preventing crystallization and clogging of chemical metering pumps, dosing lines, and spray nozzles during application.\u003c\/p\u003e\u003cp\u003eUtilizing the incorrect concentration or an unverified grade can lead to severe system failure modes. In wastewater treatment, a concentration lower than 40% disrupts the stoichiometric ratio required for optimal coagulation, leading to incomplete flocculation, excessive chemical consumption, and elevated levels of suspended solids in the effluent. Conversely, attempting to use anhydrous solid or highly concentrated forms increases the risk of thermal runaway during dilution and rapid corrosion of processing equipment. For advanced etching applications, customers often pair this with solutions from our \u003ca href=\"\/products\/hydrochloric-acid-37\"\u003ehydrochloric acid 37% product page\u003c\/a\u003e. By standardizing on our 40% liquid solution, operators ensure predictable reaction rates, stable pH adjustment, and continuous, automated dosing without the maintenance overhead of dry chemical preparation.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7705-08-0\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eCl3Fe\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e162.20 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e599 °F at 760 mmHg (Decomposes) (NTP, 1992)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e583 °F (NTP, 1992)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e2.8 at 68 °F (anhydrous solid) (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eFerric chloride is an orange to brown-black solid.
