  • question_answer In kjeldahl?s method, \[CuS{{O}_{4}}\] acts as [AFMC 2001]

    A) Oxidising agent

    B) Reducing agent

    C) Hydrolysing agent

    D) Catalytic agent

    Correct Answer: D

    Solution :

    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.
