Name the scientist who developed the ph scale

The pH scale that is widely accepted and used by scientists didn't actually exist until 1909. Before then scientists had to rely on using adjectives to describe the acidity or basicity of a substance they were working with. That scale was created by S. P. L. Sørensen, a Danish chemist who was working in Copenhagen at the time of his creation. The chemist was honored with an interactive What is the pH scale? The pH scale is used to classify the level of acidity a basicity of a substance. The scale is numbered from zero through to 14, and on modern scales each number has a corresponding color on a spectrum. Today we have pH strips, pieces of paper that react with a substance's acidity or basicity and change color when they come in contact with one of them. The color the strip turns to after it comes in contact with the substance corresponds to a spot on the pH color spectrum. Water is usually neutral, Six facts about S. P. L. Sørensen: S. P. L. Sørensen's full name was In 1901 he took on the role of the director of the chemical department at the Carlsberg Laboratory, the lab of the beer company Carlsberg. His wife, The Sørensen's creation allowed brewers at the Carlsberg lab to follow the fermentation process in beer production to make sure it was on track. He originally planned to study medicine, but changed career paths when he was in school.

John Dalton was the one who gave the atomic theory of matter. The atomic theory of matter: • Matter is made up of small particles called atoms that cannot be divided. • All the atoms of an element are the same with respect to shape, size, and structure. • All the compounds are made up of atoms that are combined in a simple fixed ratio.

Industry laboratories, while intended to advance practical industrial processes, can also be the birthplace of theoretical concepts. Such was the case with the concept of pH, introduced in 1909 by Søren Sørensen as a convenient way of expressing acidity—the negative logarithm of hydrogen ion concentration. At the Carlsberg Laboratory Sørensen (1868–1939), who held a PhD from the University of Copenhagen, directed the chemical department of the Carlsberg Laboratory, which was supported by the beer company of the same name, brewing being one of the oldest chemical industries. At the time, he was working on the effect of ion concentration in the analysis of proteins. Sørensen subsequently became a leader in the application of thermodynamics to protein chemistry, and in this work he was assisted by his wife, Margrethe Høyrup Sørensen. The pH Scale The context for the introduction of the concept of pH was the slow changeover from the old color-change tests for indicating the degree of acidity or basicity to electrical methods. In the latter technique the current generated in an electrochemical cell by ions migrating to oppositely charged electrodes was measured, using a highly sensitive (and delicate) galvanometer. Until Sørensen developed the pH scale, there was no widely accepted way of expressing hydrogen ion concentrations. Featured image: Undated photo of Danish chemist Soren Sorensen working in a lab.

Google celebrated the life of Søren Peder Lauritz (S.P.L.) Sørensen on Tuesday with an interactive homepage doodle that pays tribute to the Danish chemist. While Sørensen was working as the chemical director of Carlsberg Laboratories, the operations affiliated with the Carlsberg brewery, he developed the logarithmic pH scale that measures the acidity or basicity of a solution. A massive discovery for which he’s best come to be known, the scale helps scientists understand the chemical composition of liquids, and its discovery has been invaluable. Sørensen was born in 1868 in Havrebjerg, a small town that is today home to around 500 people. At the age of 18, he went to study at the University of Copenhagen, studying chemistry after being influenced by Sophus Mads Jørgensen. Sørensen didn’t spend his whole life working as a chemist, as he also briefly worked in consultancy for the royal naval dockyard. In 1901 he took up his position at the Carlsberg Laboratories, an institute established in 1876 by brewery founder J.C. Jacobsen to further the development of beer. It was here that Sørensen developed the scale. S. P. L.
