TranslingualEdit
Etymology 1Edit
Originally introduced in 1909 by S. P. L. Sørensen, using the notation pH+ for what he called the “hydrogen ion exponent” (Wasserstoffionenexponent ) of a solution. He may have chosen the symbol p arbitrarily; another suggestion is that it abbreviates German Potenz (“power”). The “H” is the international chemical symbol for the element hydrogen.
