What is the titration invented by the Danish chemist famous for the concept of pH used for?
Sørensen formol titration The Sørensen formol titration(SFT) invented by S. P. L. Sørensen in 1907 is a titration of an amino acid with potassium hydroxide in the presence of formaldehyde. It is used in the determination of protein content in samples.
Total inorganic carbon The total inorganic carbon ("C", or TIC) or dissolved inorganic carbon (DIC) is the sum of inorganic carbon species in a solution. The inorganic carbon species include carbon dioxide, carbonic acid, bicarbonate anion, and carbonate. It is customary to express carbon dioxide and carbonic acid simultaneously as CO* . "C" is a key parameter when making measurements related to the pH of natural aqueous systems, and carbon dioxide flux estimates.
