Company: 涞水县燕南精细化工有限公司

Product Description: Potassium ferricyanide, with the chemical formula K₃[Fe(CN)₆], is an inorganic compound belonging to the category of coordination compounds. The following is a detailed introduction about it:Basic Properties1. Appearance: Deep red crystals, highly soluble in water, yielding a yellow-green aqueous solution.2. Oxidizing Property: Exhibits mild oxidizing behavior, particularly participating in redox reactions under light or acidic conditions.3. Stability: Relatively stable in neutral or alkaline solutions; decomposes upon contact with acids to produce highly toxic substances. Avoid exposure to strong acids.Main Applications1. Laboratory Reagent:   Used to detect Fe²⁺ (ferrous ions), forming a deep blue precipitate of Prussian blue (Fe₄[Fe(CN)₆]₃).   Serves as an oxidizing agent or electron transfer mediator in electrochemistry.2. Industrial Applications:   Photographic Processes: Functions as a bleaching or toning agent (e.g., cyanotype printing).   Metal Plating: Utilized in processes such as zinc or silver plating.   Pigment Production: Synthesizes blue pigments like Prussian blue.3. Other Uses:   Blueprint Making: Reproduction of engineering drawings.   Certain Food Additives: Acts as an anti-caking agent (must comply with safety standards).Safety PrecautionsToxicity: Low toxicity, but decomposition products (e.g., HCN) are extremely hazardous. Avoid contact with acids and ensure proper ventilation during handling.Protection: Wear gloves and goggles to prevent inhalation of dust or skin contact.Storage: Store in a sealed, light-protected container away from acidic substances.Difference from Potassium FerrocyanidePotassium ferrocyanide (K₄[Fe(CN)₆]) is the reduced form of potassium ferricyanide, exhibiting greater chemical stability. It is commonly used as an anti-caking agent in food (e.g., added to table salt as "potassium ferrocyanide"). The two should not be confused.---###  more>
