Outline the essential steps and the chemistry involved in the qualitative and quantitative determination of nitrogen (Kjeldahl's method) in an organic compound. Describe briefly the principles and procedures involved in the determination of the presence of halogen in an organic compound which contains no nitrogen or sulphur. Write equations for the essential reactions involved in the procedures. Explain briefly the procedure and the chemistry involved in the quantitative determination of carbon and hydrogen in an organic compound.
Answer (2)
Kjeldahl's method involves digestion, neutralization, distillation, and titration for nitrogen determination. Halogen presence is identified by reacting with sodium to form sodium halide. Carbon and hydrogen quantification is achieved through combustion analysis, measuring CO2 and H2O produced from burning the sample.
