The first step in the Kjeldahl Nitrogen Analysis is to digest the organic sample with boiling sulfuric acid to convert nitrogen to ammonium. This is followed by neutralizing the ammonium to release ammonia, which is then distilled into standard hydrochloric acid. Finally, any unreacted standard hydrochloric acid is titrated with sodium hydroxide. Therefore, the correct order is III, II, I, IV.
