Google Doodle is celebrating the founder of pH, SPL Sorensen

Google Doodle today is celebrating the founder of pH who is a Danish biochemist Soren Peder Lauritz Sorensen. He did a revolutionary creation in the chemistry as well as Biology world by introducing the concept of pH scale which measures the acidity or alkalinity of any substances.

SPL Sorensen was the first scientist to bring the light on the concept of pH scale. He heads the Carlsberg Laboratory in Denmark’s capital, Copenhagen from 1901 to 1938.

He studied the effects of the hydrogen ion concentration and later on lands up to the idea of simply developing a scale to measure the ions in 1909 as an outcome of which pH scale was born.

SPL Sorensen was born in Havebjerb, a Danish city on 9th January 1868. The Doodle is celebrating the creation of pH by playing a game with the user by showing different substance including food items and differentiate it according to the pH values by simple making a guess.

If the guess is correct, google will show the exact pH value of the said substance and it is wrong, then an animated figure modelled as Sorensen will shake his head and ask you to try again. After the final guess of the six substances, they all animate again and later makes the google logo.

The pH for the common food items can easily be detected by the pH scale as pH level for eggs stands at 8 while lemons and tomatoes stand at 2 and 4 respectively.

The pH scale is widely used in chemical laboratories for measuring the acidity or alkalinity and helpful to detect the pH of the body and maintain the balance. The pH scale ranges from 0 to 14 pH values. The value of 7 is considered as neutral while any value below 7 is considered as acidic and above 7 have the basic nature.
