317524
Assertion :
The Duma's method is more appicable to nitrogen containing organic compounds than the Kjeldahl's method.
Reason :
The Kjeldahl's method does not give satisfactory results for compounds in which nitrogen is directly linked to oxygen.
317525 During estimation of nitrogen present in an organic compound by Kjeldahl's method, the ammonia evolved from 0.5 g of the compound in Kjeldahl's estimation of nitrogen, neutralized 10 mL of \(1 \mathrm{M} \,\mathrm{H}_{2} \mathrm{SO}_{4}\). Find out the percentage of nitrogen in the compound.

In Kjeldahl's method for the estimation of \(\mathrm{N}_{2}\), potassium sulphate and copper sulphate are used. On the basis of their functions which of the following statement(s) is/are correct?
(I) Potassium sulphate raises the b.pt. and ensures complete reaction.
(II) Copper sulphate acts as catalyst.
(III)Potassium sulphate acts as catalyst and copper sulphate raises the b.pt.
