Analytical Chemistry Question 174
Question: In Kjeldahl’s method, $ CuSO_4 $ acts as
Options:
A) oxidising agent
B) reducing agent
C) hydrolysing agent
D) catalytic agent
Show Answer
Answer:
Correct Answer: D
Solution:
[d] Kjeldahl’s method depends upon the fact that most of the organic compounds containing nitrogen are quantitatively decomposed to give $ {{(NH_4)}_2}SO_4 $ when heated strongly with conc. $ H_2SO_4 $ . In this method $ CuSO_4 $ acts as catalytic agent.
