What is Ferric Pyrophosphate?
Ferric pyrophosphate is a coordination compound formed from iron (III) ions and pyrophosphate ions. Its chemical formula is typically represented as Fe2(P2O7)3. This compound is often used in food fortification, particularly in iron supplements, as it provides a bioavailable source of iron. Additionally, it finds applications in the pharmaceutical industry and as a catalyst in various chemical reactions.
Molecular Weight of Ferric Pyrophosphate
The molecular weight of ferric pyrophosphate can be calculated by summing the atomic weights of its constituent elements. The key components include:
– Iron (Fe): Atomic weight = 55.845 g/mol
– Phosphorus (P): Atomic weight = 30.974 g/mol
– Oxygen (O): Atomic weight = 15.999 g/mol
For ferric pyrophosphate, the empirical formula can be represented as Fe2(P2O7)3. To calculate its molecular weight:
1. Calculate the contribution of Iron:
– There are 2 iron atoms: 2 × 55.845 g/mol = 111.690 g/mol
2. Calculate the contribution of Phosphorus:
– There are 4 phosphorus atoms (2 per pyrophosphate unit and 3 units): 4 × 30.974 g/mol = 123.896 g/mol
3. Calculate the contribution of Oxygen:
– There are 21 oxygen atoms (7 per pyrophosphate unit and 3 units): 21 × 15.999 g/mol = 335.979 g/mol
4. Sum all contributions:
– Total molecular weight = 111.690 g/mol + 123.896 g/mol + 335.979 g/mol = 571.565 g/mol
Thus, the molecular weight of ferric pyrophosphate is approximately 571.57 g/mol.
