Ferric pyrophosphate, also known as iron(III) pyrophosphate, is an important chemical compound that has garnered attention in various fields, including nutrition, medicine, and material science. One of the crucial aspects of this compound is its molecular weight, which plays a significant role in its applications and effectiveness. In this article, we will explore what ferric pyrophosphate is, its molecular weight, and why this information is essential.
What is Ferric Pyrophosphate?
Ferric pyrophosphate is a coordination compound that consists of iron in its +3 oxidation state and pyrophosphate ions. Its chemical formula is typically represented as Fe2(H2P2O7)3. This compound is used primarily as a source of iron in dietary supplements and in the food industry, particularly to fortify products with iron.
Applications of Ferric Pyrophosphate
1. Nutritional Supplements: Ferric pyrophosphate is often used in iron supplements as it provides a bioavailable form of iron that can help prevent or treat iron deficiency anemia.
2. Food Fortification: It is commonly added to various food products to enhance their iron content, making it beneficial for populations at risk of iron deficiency.
3. Industrial Uses: In material science, ferric pyrophosphate is investigated for its properties in catalysis and as a pigment in various applications.
Molecular Weight of Ferric Pyrophosphate
The molecular weight of ferric pyrophosphate is calculated based on the atomic weights of its constituent elements. The molecular formula, Fe2(H2P2O7)3, indicates that each molecule contains:
– 2 iron (Fe) atoms
– 6 oxygen (O) atoms
– 4 phosphorus (P) atoms
– 6 hydrogen (H) atoms
To determine the molecular weight, we use the following atomic weights (approximate values):
– Iron (Fe): 55.85 g/mol
– Phosphorus (P): 30.97 g/mol
– Oxygen (O): 16.00 g/mol
– Hydrogen (H): 1.01 g/mol
Calculation
Using the formula, we can calculate the molecular weight as follows:
– Iron: 2 × 55.85 = 111.70 g/mol
– Phosphorus: 4 × 30.97 = 123.88 g/mol
– Oxygen: 6 × 16.00 = 96.00 g/mol
– Hydrogen: 6 × 1.01 = 6.06 g/mol
Now, summing these values:
\[
\text{Molecular Weight} = 111.70 + 123.88 + 96.00 + 6.06 = 337.64 \, \text{g/mol}
\]
Thus, the molecular weight of ferric pyrophosphate is approximately 337.64 g/mol.
Importance of Molecular Weight in Applications
Understanding the molecular weight of ferric pyrophosphate is critical for several reasons:
1. Dosage Calculations: For dietary supplements and food fortification, knowing the molecular weight helps in calculating the appropriate dosage to ensure efficacy without causing toxicity.
2. Chemical Reactions: In industrial applications, the molecular weight plays a role in stoichiometry, helping chemists predict how much of a reactant is needed for a reaction.
3. Bioavailability Assessment: In nutritional science, the molecular weight can influence how well the body absorbs and utilizes iron from ferric pyrophosphate compared to other iron sources.
Conclusion
Ferric pyrophosphate is a vital compound with a molecular weight of approximately 337.64 g/mol. Its applications in nutrition and industry highlight the importance of understanding its properties, including molecular weight. By knowing the molecular weight, professionals can make informed decisions regarding its use in supplements, food products, and chemical processes.
