Which of the following statements is/are correct regarding the digestion step in Kjeldahl's method f — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

During Kjeldahl digestion, the organic compound is heated with concentrated $H_2SO_4$. $K_2SO_4$ is added to elevate the boiling point of the acid, ensuring a higher reaction temperature. $CuSO_4$ acts as a catalyst. The goal is to quantitatively convert organic nitrogen into ammonium sulphate, $(NH_4)_2SO_4$. Nitric acid is not used here.
