Dumas method, Kjeldahl’s method
Differentiate between the principle of estimation of nitrogen in an organic compound by Kjeldahl’s method.
A sample of 0.50 g of an organic compound was treated according to Kjeldahl’s method. The ammonia evolved was absorbed in 50 mL of 0.5 M H2SO4. The residual acid required 60 mL of 0.5 M solution of NaOH for neutralisation. Find the percentage composition of nitrogen in the compound.
