WebbThe pH value is therefore defined as the negative logarithm of the hydrogen ion concentration. Sorensen created the term pH, which stands for hydrogen ion potential. Negative logarithms are expressed by P. Molecules/liter and moles/liter are the units of concentration for H30+. In pH, why is H capitalized and p is small? Webb10 logarithm (i.e. the decimal logarithm) of the molar concentration of hydrogen ions in the solution. More precisely, pH is the negative of the base 10 logarithm of the activity of the H+ ion. At 25 °C, solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.
