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.
Elizabeth Fulhame Elizabeth Fulhame (fl. 1794) was a Scottish chemist who invented the concept of catalysis and discovered photoreduction. She describes catalysis as a process at length in her 1794 book "An Essay On Combustion with a View to a New Art of Dying and Painting, wherein the Phlogistic and Antiphlogistic Hypotheses are Proved Erroneous." The book relates in painstaking detail her experiments with oxidation-reduction reactions, and the conclusions she draws regarding Phlogiston theory, in which she disagrees with both the Phlogistians and Antiphlogistians.
