This article delves into its chemical formula, properties, and practical uses, making it a valuable resource for students, researchers, and professionals alike.
What is Iron (11) Phosphate?
Iron (11) phosphate, also known as ferrous phosphate, is a compound composed of iron in the +2 oxidation state (Fe²⁺) combined with phosphate ions (PO₄³⁻). The chemical formula for iron (11) phosphate is Fe3(PO4)2. This notation indicates that three iron ions are associated with two phosphate groups in the compound.
Chemical Composition
The chemical formula Fe3(PO4)2 can be broken down as follows:
– Fe (Iron): The central element in this compound, iron, is present in a +2 oxidation state.
– PO₄ (Phosphate): A polyatomic ion, phosphate consists of one phosphorus atom surrounded by four oxygen atoms, carrying a -3 charge.
Molecular Weight
To understand its properties better, it is essential to calculate the molecular weight of iron (11) phosphate. The molecular weight can be calculated using the atomic weights of its constituent elements:
– Iron (Fe): approximately 55.85 g/mol
– Phosphorus (P): approximately 30.97 g/mol
– Oxygen (O): approximately 16.00 g/mol
Using the formula:
– Molecular Weight of Fe3(PO4)2 = (3 × 55.85) + (2 × (30.97 + (4 × 16)))
– = 167.55 + 2 × (30.97 + 64)
– = 167.55 + 2 × 94.97
– = 167.55 + 189.94
– = 357.49 g/mol
Thus, the molecular weight of iron (11) phosphate is approximately 357.49 g/mol.
