1.	In Khcldahl's methofd for the estimation of N_(2), potassium suphate and copper sulphate are used. On the basis of their functions which of the following statement(s) is /are correct? (i). Potassium sulphate raises theb.pt. and ensures complete reaction(ii). Copper sulphate act as Catalyst (iii). Potassium sulphate acts as catalyst and copper sulphate raises the b.pt.
Answer» Only (iii) is CORRECT (i) and (II) are correct Only (ii) is correct None of these Solution :`K_(2)SO_(4)` raises b.pt. and `CuSO_(4)` act as CATALYST.
