Method, organic compounds are treated with sodium metal and heated in a test tube. This process converts the organic compounds into their respective sodium salts. The test tube is then cooled, and water is added to dissolve the sodium salts. The solution is then filtered, and the filtrate is treated with dilute sulfuric acid to form sodium sulfate. This step helps to remove any unwanted impurities. Next, the solution is treated with a small amount of ferrous sulfate and heated. This forms a deep blue precipitate of Prussian blue, which indicates the presence of nitrogen in the organic compound. Finally, the precipitate is filtered, washed, and dried, and its weight is measured to determine the amount of nitrogen present in the original organic compound.
