MCQ
In kjeldahl’s method, $CuS{O_4}$ acts as
  • A
    Oxidising agent
  • B
    Reducing agent
  • C
    Hydrolysing agent
  • ✓
    Catalytic agent
✓

Answer

Correct option: D.
Catalytic agent
d
(d)Kjeldahl’s method depends upon the fact that most of the organic compounds containing nitrogen are quantitatively decomposed to give ${(N{H_4})_2}S{O_4}$when heated strongly with conc. ${H_2}S{O_4}$. In this method $CuS{O_4}$ acts as catalytic agent.
