Iron(III) ethylenediaminetetraacetate (EDTA) complex, also known as Sodium Ferric EDTA, is synthesized in a reaction involving Iron(III) chloride, Ethylenediaminetetraacetic acid (EDTA), and Sodium hydroxide. Here's a step-by-step guide for a potential synthesis: 1. Add a known amount of Iron(III) chloride hexahydrate to distilled water to create an Iron(III) chloride solution. 2. Mix Ethylenediaminetetraacetic acid (EDTA) with distilled water to form an EDTA solution. 3. Slowly add the Iron(III) chloride solution to the EDTA solution with constant stirring. 4. A yellowish Iron-EDTA complex will start to form. 5. Gradually, add Sodium hydroxide (NaOH) solution to the mixture to adjust the pH to around 7-8. At this pH, most of the Iron-EDTA complex will be converted to its sodium salt, Na[Fe(EDTA)]*3H2O. 6. Allow the solution to precipitate and then decant or filter the solution to remove any unreacted substances. 7. Finally, dry the product to yield the solid Sodium Ferric EDTA complex. Remember to always work under appropriate safety measures while working with chemicals. Wear the appropriate protective equipment, such as goggles, gloves and lab coat, and keep a first aid kit nearby. Make sure not to inhale or ingest any of the chemicals, and always work in a well-ventilated area. Also, remember that the synthesis should be carried out under supervision if you're not familiar with handling these substances or performing such procedures. Always follow the school or institution's safety guidelines when performing such experiments.
