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 ...

What Is Soil pH? A solution’s pH is a numerical rating of its acidity or alkalinity. All pH is measured on a logarithmic scale from zero (most acidic) to 14 (most alkaline, or basic); 7.0 is ...

For those who don't remember back to Chem 101, the pH scale is the negative of the base 10 logarithm of the activity of the hydrogen ion. Solutions with a pH less than 7 are acidic and solutions ...

"Logarithmic scales are commonly used in other sciences, for example, the decibel scale in sound measurements and the pH scale in chemistry for rating acidity." ...

Sørensen was the first to create a pH scale that was easy for chemists to use to classify acidity and basicity.

The Richter scale measures the amount of energy released during an earthquake, but it does so indirectly, using a mathematical adjustment called a logarithm (if the last time you heard about ...
