In Kjeldahl's method, organic N is estimated as

Options

  1. Anitrogen
  2. Bammonia
  3. Cnitric acid
  4. Dnitrogen dioxide

Correct answer

B. ammonia

Step-by-step solution

In Kjeldahl procedure, after digestion in concentrated sulphuric acid, the total organic N is converted to ammonium sulphate and ammonia is formed. When it is distilled into boric acid solution under alkaline conditions. It is a method for quantitative determination of nitrogen contained in organic substances plus the nitrogen contained in inorganic compounds.
