Understanding the Molar Mass of NaFeEDTA·3H2O

When it comes to chemistry, understanding the molar mass of compounds is crucial for various applications, including stoichiometry, solution preparation, and analytical calculations. One such compound that often comes up in studies related to iron and nutrition is Sodium Iron EDTA, specifically in its trihydrate form, NaFeEDTA·3H2O. In this article, we will explore the molar mass of NaFeEDTA·3H2O, its significance, and applications.

What is NaFeEDTA·3H2O?

NaFeEDTA·3H2O is a coordination compound where EDTA (ethylenediaminetetraacetic acid) acts as a chelating agent, binding to iron (Fe) ions. The “Na” stands for sodium, which balances the charge in the compound. The “3H2O” indicates that there are three water molecules associated with each molecule of NaFeEDTA, making it a hydrated form of the compound.

Calculating the Molar Mass

To understand the molar mass of NaFeEDTA·3H2O, we need to consider the molar masses of each constituent element. Here’s a breakdown of the components:

– Sodium (Na): Approximately 22.99 g/mol
– Iron (Fe): Approximately 55.85 g/mol
– Carbon (C): Approximately 12.01 g/mol (There are 8 carbon atoms in EDTA)
– Hydrogen (H): Approximately 1.01 g/mol (There are 13 hydrogen atoms in EDTA plus 6 from the 3 water molecules)
– Nitrogen (N): Approximately 14.01 g/mol (There are 2 nitrogen atoms in EDTA)
– Oxygen (O): Approximately 16.00 g/mol (There are 8 oxygen atoms in EDTA plus 3 from the 3 water molecules)

Molar Mass Calculation

1. Sodium (Na): 22.99 g/mol
2. Iron (Fe): 55.85 g/mol
3. EDTA (C10H12N2O8):
– Carbon: \(8 \times 12.01 = 96.08\) g/mol
– Hydrogen: \(12 \times 1.01 = 12.12\) g/mol
– Nitrogen: \(2 \times 14.01 = 28.02\) g/mol
– Oxygen: \(8 \times 16.00 = 128.00\) g/mol
– Total for EDTA: \(96.08 + 12.12 + 28.02 + 128.00 = 264.22\) g/mol
4. Water (3H2O): \(3 \times (2 \times 1.01 + 16.00) = 3 \times 18.02 = 54.06\) g/mol

Total Molar Mass of NaFeEDTA·3H2O

Now, we can sum everything up:
– Sodium: 22.99 g/mol
– Iron: 55.85 g/mol
– EDTA: 264.22 g/mol
– Water: 54.06 g/mol

Total Molar Mass = 22.99 + 55.85 + 264.22 + 54.06 = 397.12 g/mol

Thus, the molar mass of NaFeEDTA·3H2O is approximately 397.12 g/mol.
