MCQ
In Kjeldahl’s method of estimation of $N$, $CuS{O_4}$ acts as
- AOxidising agent
- BReducing agent
- ✓Catalytic agent
- DHydrolysis agent
✓
Answer
Correct option: C.
Catalytic agent
c
Kjeldahl's method depends upon the fact that most of the organic compounds containing nitrogen are quantitatively decomposed to give $\left( NH _4\right)_2 SO _4$ when heated strongly with conc. $H _2 SO _4$. In this method $CuSO _4$ acts as catalytic agent.
