Google Doodle pH Fun

If you pop over to search page you will be greeted by today’s Google Doodle celebrating S. P. L. Sørensen, a Danish Chemist who is famous for the introduction of the concept of pH, a scale for measuring acidity and alkalinity.

What is the pH scale?

The name of the scale stands for ‘potential of Hydrogen’ and basically measures the concentration of hydrogen ions in a solution. Seven on the pH scale is neutral (blood and water being examples of neutral substances), with lower than seven being acidic and higher than seven described as ‘base’. The scale runs from 0-14 although it is possible to go higher and lower than this in extreme circumstance.
