How do you calculate total nitrogen?

To calculate total nitrogen, you typically sum up the concentrations of different forms of nitrogen present in a sample. This can include organic nitrogen, ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen. Analytical techniques such as Kjeldahl digestion or combustion methods are commonly used to determine total nitrogen content in a sample.


What is the purpose of soda lime in the detection of nitrogen in nitrogen containing compounds?

Soda lime is used to detect the presence of nitrogen in nitrogen-containing compounds through a process called the Kjeldahl method. It is used to absorb the evolved ammonia gas during the digestion of the sample, which is then released by heating the soda lime and can be quantitatively determined. This method helps in determining the nitrogen content in organic compounds.


What is nitrogen used for in industry?

Nitrogen is used in industry for various purposes such as blanketing to prevent oxidation, purging pipelines and tanks, cryogenic applications, and as an inert gas for packaging and preserving food. It is also used in the production of chemicals and pharmaceuticals.
