Understanding Iron(II) Phosphate: Percent Composition and Its Importance
Iron(II) phosphate, often represented by the chemical formula Fe3(PO4)2, is an important compound in various industries, including agriculture, chemistry, and materials science. Understanding its percent composition can provide valuable insights into its properties and applications. In this article, we will delve into the percent composition of iron(II) phosphate, its significance, and its applications.
What is Iron(II) Phosphate?
Iron(II) phosphate is a salt formed from iron and phosphate ions. It is commonly found in nature and can be synthesized in laboratories for various purposes. The compound is known for its stability and low solubility in water, making it suitable for different applications.
Chemical Composition
To calculate the percent composition of iron(II) phosphate, we first need to understand its molecular formula: Fe3(PO4)2. This indicates that each formula unit contains three iron (Fe) atoms and two phosphate (PO4) groups.
Molar Mass Calculation
1. Iron (Fe):
– Atomic mass = 55.85 g/mol
– Contribution from 3 iron atoms = 3 × 55.85 = 167.55 g/mol
2. Phosphate (PO4):
– Atomic mass of phosphorus (P) = 30.97 g/mol
– Atomic mass of oxygen (O) = 16.00 g/mol
– Contribution from one phosphate group = 30.97 + (4 × 16.00) = 30.97 + 64.00 = 94.97 g/mol
– Contribution from 2 phosphate groups = 2 × 94.97 = 189.94 g/mol
3. Total Molar Mass of Iron(II) Phosphate:
– Total = 167.55 g/mol (from Fe) + 189.94 g/mol (from PO4) = 357.49 g/mol
Percent Composition Calculation
Now, we can calculate the percent composition of iron(II) phosphate:
– Percent of Iron (Fe):
\[
\text{Percent Fe} = \left( \frac{167.55 \, \text{g/mol}}{357.49 \, \text{g/mol}} \right) \times 100 \approx 46.87\%
\]
– Percent of Phosphorus (P):
\[
\text{Percent P} = \left( \frac{61.94 \, \text{g/mol}}{357.49 \, \text{g/mol}} \right) \times 100 \approx 17.33\%
\]
– Percent of Oxygen (O):
\[
\text{Percent O} = \left( \frac{64.00 \, \text{g/mol}}{357.49 \, \text{g/mol}} \right) \times 100 \approx 17.92\%
\]
Summary of Percent Composition
– Iron (Fe): 46.87%
– Phosphorus (P): 17.33%
– Oxygen (O): 35.80%
