To synthesize the iron(III) ethylenediaminetetraacetate (EDTA) complex, Na[Fe(EDTA)]·3H2O, you can follow these steps: Materials needed: 1. Iron (III) chloride hexahydrate (FeCl3.6H2O) 2. Disodium salt of ethylenediaminetetraacetic acid (Na2EDTA) 3. Sodium hydroxide (NaOH) 4. Distilled water 5. Standard laboratory glassware (e.g., beakers, burettes, funnels) Procedure: 1. Dissolve a reasonable amount of FeCl3.6H2O in distilled water in order to prepare an aqueous solution. 2. In a separate container, make a solution of Na2EDTA. Ensure that it completely dissolves in the water. 3. Slowly add the solution of Na2EDTA to the iron(III) solution under constant stirring. A reddish-brown complex will form. 4. Adjust the pH of the mixture to approximately 7 with the help of sodium hydroxide (NaOH) solution. The iron(III) ethylenediaminetetraacetate complex precipitates out at this pH. 5. Filter the precipitate and wash it several times with distilled water to remove any unreacted reagents. 6. Leave the precipitate in an open environment to allow it to crystallize and dry naturally. Remember that standard safety precautions should be taken when dealing with chemical substances. Always wear appropriate protective gear (gloves, lab coat, goggles), operate in a well-ventilated area or a fume hood, and handle all chemicals appropriately. If you are unsure about any step in this process, it is recommended that you consult with a qualified chemist. Please note that this is an illustrative method. Conditions such as concentration, temperature, pH etc. should be optimized depending on the exact application of this compound. Make sure you dispose of any chemical waste properly in accordance with local regulations or instructions given by your chemistry instructor or lab supervisor. All the chemicals used in this method are harsh and can cause harm if mishandled. The procedure should only be carried out by a trained individual in a controlled laboratory environment.
