What is the role of in Kjeldahl solution during digestion. |
|
Answer» ldhal digestion process comprises of warming a substance with sulphuric acid, which decays the natural substance by oxidation to free the decreased nitrogen as ammonium sulfate. The obtained product is then refined with a little amount of SODIUM HYDROXIDE, which changes over the ammonium salt to alkali. In the Kjeldhal technique, sodium or potassium sulfate is utilized to lift the boiling point of sulfuric acid from 180°C to 400°C. Such high temperatures are fundamental to ACCOMPLISHING the DISPOSAL of natural issue and maintenance of the nitrogen in a STEADY mineral frame (ammonium sulfate). |
