Understanding Sodium Iron EDTA: Molecular Weight and Its Importance

Sodium Iron EDTA, also known as Sodium Ferric Ethylenediaminetetraacetic Acid, is a chelating agent widely used in various industries, including agriculture, pharmaceuticals, and food processing. One of the key aspects of Sodium Iron EDTA that researchers and manufacturers often examine is its molecular weight. In this article, we will delve into the molecular weight of Sodium Iron EDTA, its significance, and its applications.

What is Sodium Iron EDTA?

Sodium Iron EDTA is a complex compound formed by the reaction of iron with ethylenediaminetetraacetic acid (EDTA) and sodium. This compound is particularly valued for its ability to bind iron ions, making them more bioavailable for plants and animals. By forming a stable complex, Sodium Iron EDTA prevents iron from precipitating, ensuring that it can be easily absorbed in biological systems.

Molecular Weight of Sodium Iron EDTA

The molecular weight of Sodium Iron EDTA is an important factor in its application and usability. The molecular formula for Sodium Iron EDTA is typically represented as C10H12N2O8FeNa. To calculate its molecular weight, we need to sum the atomic weights of all the atoms in the formula:

– Carbon (C) = 12.01 g/mol
– Hydrogen (H) = 1.01 g/mol
– Nitrogen (N) = 14.01 g/mol
– Oxygen (O) = 16.00 g/mol
– Iron (Fe) = 55.85 g/mol
– Sodium (Na) = 22.99 g/mol

Using the molecular formula:
– Carbon: 10 × 12.01 = 120.1 g/mol
– Hydrogen: 12 × 1.01 = 12.12 g/mol
– Nitrogen: 2 × 14.01 = 28.02 g/mol
– Oxygen: 8 × 16.00 = 128.00 g/mol
– Iron: 1 × 55.85 = 55.85 g/mol
– Sodium: 1 × 22.99 = 22.99 g/mol

Adding these together gives us a total molecular weight of approximately 421.24 g/mol for Sodium Iron EDTA. This value is essential for manufacturers and researchers when formulating products containing this compound.
