Funny how people are so certain it's "potential". In high school I was taught it was "power" - which suggests a negative logarithm even less

Definitely sending this to my dad, a retired biologist who writes his initials as pH. Also sending the best answers.

i propose it stands for "problem". unfortunately, this actually results in a incredible increase in the number of problems we have to solve, but fortunately the new ones are all very small

Scientists need to pick one: either pH has to do with protons, or atomic nuclei consist of neutrons and hydrogen ions

it was just his unorganized way of thinking/explaining. It's just ph in the same manner that it's common to use p1, p2 etc. It's just put there as an undetermined p variable for hydrogen.

Th guy who introduced the term apparently liked to use p and q as variable names. So the answer is: it's pH because it isn't qH.

I think the two leading theories are "pondus hydrogenii" which means the potential of hydrogen and was something that was used in later Carlsberg publications. The other which was presented in the book "pH – en dansk idé!" is you have q and p, q has a known acidity and p has a unknown acidity.

P is for practical joke. Started by Sørenssen by introducing a random letter without explaining the meaning, and is now one of the longest running jokes in history.

Why does everyone get this wrong? "p" is an operator. It means the negative log. pH is the negative log of the concentration of H+ ions.

Was it not "power" of hydrogen? I can't remember if that was from Mrs. Novak or Dr. Lloyd.
