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.
