Understanding Iron(II) Acetate: The Basics of Fe(C2H3O2)2 and Its Molar Mass

Iron(II) acetate, a chemical compound with the formula Fe(C2H3O2)2, is an important iron salt used in various industrial and laboratory applications. This article will delve into the structure, properties, and uses of iron(II) acetate, along with a detailed explanation of its molar mass.

What is Iron(II) Acetate?

Iron(II) acetate, also known as ferrous acetate, consists of iron in its +2 oxidation state. The compound is formed by the reaction of acetic acid with iron(II) oxide or iron(II) hydroxide. The chemical formula Fe(C2H3O2)2 indicates that each iron ion (Fe²⁺) is coordinated with two acetate ions (C2H3O2⁻).

Chemical Structure

The structure of iron(II) acetate features a central iron ion surrounded by two acetate groups. Each acetate group acts as a bidentate ligand, forming coordinate covalent bonds with the iron ion. This configuration contributes to the compound’s stability and solubility in water.

Molar Mass of Iron(II) Acetate

Calculating the molar mass of iron(II) acetate is essential for various applications, including stoichiometry in chemical reactions. To find the molar mass, we sum the molar masses of all the constituent atoms in the formula Fe(C2H3O2)2.

Breakdown of Molar Mass Calculation

1. Iron (Fe): The molar mass of iron is approximately 55.85 g/mol.
2. Carbon (C): The molar mass of carbon is about 12.01 g/mol. Since there are 4 carbon atoms in the formula (2 from each acetate), the total for carbon is:
\( 4 \times 12.01 \, \text{g/mol} = 48.04 \, \text{g/mol} \)
3. Hydrogen (H): The molar mass of hydrogen is approximately 1.01 g/mol. There are 6 hydrogen atoms in the formula (3 from each acetate), giving us:
\( 6 \times 1.01 \, \text{g/mol} = 6.06 \, \text{g/mol} \)
4. Oxygen (O): The molar mass of oxygen is about 16.00 g/mol. With 4 oxygen atoms in total (2 from each acetate), we have:
\( 4 \times 16.00 \, \text{g/mol} = 64.00 \, \text{g/mol} \)

Total Molar Mass Calculation

Now, we can add these values together to find the total molar mass of iron(II) acetate:

\[
\text{Molar Mass of Fe(C2H3O2)2} = 55.85 \, \text{g/mol (Fe)} + 48.04 \, \text{g/mol (C)} + 6.06 \, \text{g/mol (H)} + 64.00 \, \text{g/mol (O)} = 173.95 \, \text{g/mol}
\]

Therefore, the molar mass of iron(II) acetate, Fe(C2H3O2)2, is approximately 173.95 g/mol.

Applications of Iron(II) Acetate

Iron(II) acetate has several applications:

1. Laboratory Reagent: Used as a source of iron(II) ions in various chemical reactions and analyses.
2. Pigment Production: Employed in the synthesis of iron-based pigments.
3. Nutrient Supplement: Sometimes included in dietary supplements to provide iron.
