pHstands for potenz Hydrogen "power of Hydrogen"

1. The pH, a unit of measuring hydrogen ions in solution, was discovered by the Danish scientist Søren Peder Lauritz Sørensen. While the H simply stands for the Hydrogen molecule that this unit measures, the p stands for "potenz," which in German means power. This acronym also works in French "pouvior Hydrogen," also meaning "power of Hydrogen."
