Product Description

Product Description

Ammonium Iron(III) Oxalate
Ammonium iron(III) oxalate, also known as, is an inorganic coordination compound with significant applications in chemistry and industry. Below is a detailed introduction:
Basic Information

• Chemical Name: Ammonium iron(III) oxalate, ferric ammonium oxalate
• CAS Number: 14221-47-7, 13268-42-3
• Molecular Formula:
  • Hydrated form: (NH4)3Fe(C2O4)3⋅3H2O
• Molar Mass: ~428.07 g/mol (hydrated form)
• Appearance: Light yellow-green monoclinic crystals (hydrated), often appearing as a crystalline powder.

Physical and Chemical Properties

1. Physical Properties
   • Density: ~1.78 g/cm³ (hydrated)
   • Melting Point: Decomposes before melting; loses crystalline water at 100 °C and starts decomposing at 165 °C.
   • Solubility:
     • Soluble in water (forms a green solution), insoluble in ethanol and other organic solvents.
     • Aqueous solutions are slightly acidic due to the hydrolysis of ammonium ions.
   • Photosenstivity: Highly sensitive to light, gradually decomposing into iron(II) oxalate, ammonium oxalate, and carbon dioxide upon exposure to light.
2. Chemical Properties
   • Coordination Structure: Contains an octahedral [Fe(C2O4)3]3− complex ion, where iron(III) is coordinated with three bidentate oxalate ligands.
   • Redox Reactions:
     • Under light, the iron(III) ion is reduced to iron(II), releasing CO2 (photocatalytic decomposition).
     • Reacts with strong acids (e.g., H2SO4) to release oxalic acid; reacts with bases to precipitate iron(III) hydroxide.
   • Thermal Decomposition:(NH4)3Fe(C2O4)3⋅3H2OΔNH3↑+CO2↑+FeC2O4+H2O

Applications

1. Photography and Lithography
   • Used in traditional blueprinting (cyanotype process) as a light-sensitive reagent. Upon exposure to UV light, the iron(III) complex decomposes, forming iron(II) compounds that react with potassium ferricyanide to produce blue iron(III) ferrocyanide ("Prussian blue").
   • Historically applied in photoresist coatings for printing plates and circuit boards.
2. Chemical Synthesis
   • Serves as a precursor for preparing iron-based compounds (e.g., iron nanoparticles, magnetic materials).
   • Acts as a catalyst or complexing agent in organic reactions, such as oxidation-reduction processes.
3. Analytical Chemistry
   • Used in redox titrations to standardize potassium permanganate solutions.
   • As a reagent for detecting metal ions (e.g., forming stable complexes with aluminum or zirconium ions).
4. Industrial and Agricultural Applications
   • In electroplating: As a component in metal surface treatment solutions to improve adhesion.
   • In pesticides: As an additive in certain formulations (rarely used today due to environmental concerns).
   • In textiles: For dyeing and printing as a mordant to fix dyes on fabrics.
5. Laboratory Reagent
   • Widely used in educational and research labs for demonstrating photochemical reactions, coordination chemistry, and crystal structure analysis.

Safety and Storage

1. Safety Considerations
   • Toxicity: Moderately toxic if ingested; may cause gastrointestinal irritation. Inhalation of dust irritates the respiratory tract.
   • Environmental Impact: Oxalate ions can be toxic to aquatic life in high concentrations; avoid direct discharge into water bodies.
   • Hazards: Photolabile and non-flammable, but handle with gloves and goggles to prevent skin/eye contact.
2. Storage
   • Store in opaque, airtight containers in a cool, dark, and dry place to protect from light and moisture.
   • Keep away from strong acids, bases, and oxidizing agents to prevent decomposition or reaction.
