IRON OXALATE

Iron Oxalate is a chemical inorganic compound that is denser than water. It sinks in water but is poorly soluble. It is a pale yellow solid that is soluble in dilute mineral acids. Sugar, glycerin, & many organic hydroxy acids obstruct precipitation. Many soluble carbonates, phosphates, & oxalates generate precipitation of Ferrous salts in neutral solutions. It has a rhombic crystalline structure.

Its Dihydrated form, is usually available in most volumes. High purity, submicron and nanopowder forms have a strong impression to consider. It has its other name as Ferrous oxalate. It decomposes at 150-160C. Its combustions products are iron fume or iron oxide fume. It has a flashpoint of 18.8A C.

Iron oxalate dihydrate is regarded as a key building block for the preparation of various advanced materials. Further, the pressure dependence of the crystal and molecular structure of the title compound was investigated up to p ≥ 20 GPa. It is the ferrous salt of ethandicarboxylic acid (oxalic acid). The corresponding, naturally occurring mineral is called humboldtine.

Some uses of Iron oxalate are listed below;

• It is served as a photographic developer for silver bromide-gelatin plates.
• It is used for decorative glassware.
• It acts to impart a greenish-brown tint to optical glass (sunglasses, and windshield).
• It is utilized in pigment for plastics, paints, lacquers.
• It is utilized as the light-sensitive element in the platinotype process Platinum/Palladium Printing.

Here are the benefits of it :

1. Photography: It is utilized in photography as a photosensitive material. It is commonly used in developing solutions for producing photographic prints and films. It acts as a reducing agent, facilitating the conversion of exposed silver halide crystals to metallic silver, resulting in the formation of visible images.
2. Chemical Synthesis: It serves as a precursor in the synthesis of various iron-containing compounds. It can be thermally decomposed to produce iron oxide nanoparticles, which find applications in catalysts, pigments, magnetic materials, and biomedical imaging agents.
3. Analytical Chemistry: It is employed in analytical chemistry as a standard reference material for calibrating analytical instruments, such as spectrophotometers and chromatographs. Its well-defined properties and stability make it suitable for quantitative analysis and quality control purposes.
