S.P.L. Sørensen by Kaj Linderstrøm-Lang (Book) Le pH a 80 ans. by Philippe Wéry () Most widely held works by S. L Sørensen. Sørensen’s symbol soon appeared, including p H+, P h and pH, with the latter eventually gaining dominance, largely through its official adoption by the Journal of Biological Chemistry in the decade (3).

Not everyone was pleased with Sørensen’s pro-posal. File Size: KB. Kolthoff published his first research paper in on the then newly-articulated concept of pH, which had been introduced in by the Danish chemist S. Sørensen (–). It was the first in what would become a prodigious record of published scholarship.
