in this experiemnt , i prepare Na[Fe(EDTA)]⋅3H2O
1)Dissolve 0.4 g (0.01 mol) of NaOH in 10 cm3 of water, and then add 3.8 g (0.01
mol) of Na2H2EDTA⋅2H2O.
2. Gently heat the solution until the solid dissolves to give a clear solution.
3. Dissolve 2.5 g (0.009 mol) of iron(III) chloride hexahydrate in 5 cm3 of water,
which is then added to the EDTA solution with swirling.
4. Gently boil off the water until most of the yellow powder precipitates out.
5. Cool down the solution and collect the precipitate by suction filtration.
6. Wash the product thoroughly with ice water until it is free of iron(III) ions.
7. Wash the product with ethanol twice and dry it with filter paper.
8. Weigh your product, calculate its theoretical and percentage yields.
