Understanding the Kjeldahl Method
The Kjeldahl method is a widely used technique for determining the nitrogen content in organic compounds. In this case, we are given that 1 gram of an organic compound required 58.0 ml of N/5 H2SO4 for complete neutralization of ammonia.
Calculating Moles of H2SO4 Used
- Concentration of H2SO4 = N/5
- N (Normality) of H2SO4 = 1 N (for diprotic acid)
- Therefore, N/5 = 0.2 N
Now, we convert the volume of H2SO4 used into liters:
- Volume = 58.0 ml = 0.058 L
Now, we calculate the moles of H2SO4:
- Moles of H2SO4 = Normality × Volume (in L) = 0.2 × 0.058 = 0.0116 moles
Relating Moles of H2SO4 to Ammonia
In the reaction, each mole of H2SO4 neutralizes 2 moles of NH3:
- Moles of NH3 = 2 × Moles of H2SO4 = 2 × 0.0116 = 0.0232 moles
Calculating the Mass of Nitrogen
The molar mass of nitrogen (N) is approximately 14 g/mol. Thus, the mass of nitrogen can be calculated as:
- Mass of N = Moles of N × Molar Mass = 0.0232 × 14 = 0.325 g
Calculating Percentage of Nitrogen in the Compound
To find the percentage of nitrogen in the compound:
- Percentage of N = (Mass of N / Mass of compound) × 100
- Percentage of N = (0.325 g / 1 g) × 100 = 32.5%
Conclusion
The percentage of nitrogen in the organic compound is approximately 32.5%. This calculation highlights the efficiency of the Kjeldahl method in determining nitrogen content in various organic materials.
