Have you seen the Google Doodle today? It’s brilliant. Google honors the little known creator of the pH scale, Biochemist, Søren Peder Lauritz Sørensen.
Sørensen was born in Havrebjerg, Denmark, in January 1868 into a farming family. At 18 he originally studied medicine at the University of Copenhagen, but under the influence of chemist SM Jørgensen, he decided to turn his ambitions to chemistry.
He had a fascinating career culminating in becoming the head of the Carlsberg Laboratory in Copenhagen from 1901 to 1938. While working at the Carlsberg Laboratory he studied the effect of ion concentration on proteins, exploring further the importance of the concentration of hydrogen ions. This study led to his most notable and world changing achievement – the creation of the pH Scale. He introduced the scale in 1909.
The Google Doodle is a fun, interactive game where the user can guess which items have which pH level. Why don’t you give it a try?
