In Kjeldahl's method of estimation of nitrogen, CuSO4 act as
oxidising agent
reducing agent
catalytic agent
hydrolysis agent
C.
catalytic agent
Kjeldahl's method is used for the estimation of nitrogen. The organic compound is heated with conc H2SO4 in presence of K2SO4 and a little CuSO4 to convert all the nitrogen into (NH4)2SO4.K2SO4 raises the boiling point of H2SO4 while CuSO4 catalyses the reaction.
