MCQ
In kjeldahl’s method, $CuS{O_4}$ acts as
- AOxidising agent
- BReducing agent
- CHydrolysing 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.
