In Kjeldahl's method for estimation of nitrogen, CuSO4CuSO4 acts as :JEE Main 2024 (01 Feb Shift 1)AReducing agentBCatalytic agentCHydrolysis agentDOxidising agent
Solution
In Kjeldahl's method for the estimation of nitrogen, CuSO4 acts as a Catalytic agent. This method involves the digestion of a substance in sulfuric acid, which converts organic nitrogen into ammonium sulfate. In this process, CuSO4 acts as a catalyst to speed up the reaction. Therefore, the correct answer is B. Catalytic agent.
