I'm an H⁺ denier, in that I refuse to consider loose protons to be real hydrogen, so I personally believe it stands for 'pretend'.

You need a 4 year degree to understand the wall of text in that explanation.
I was about to say "not really," but then I remembered that I have a couple of those, so yeah, probably.
I really hope you're joking. It's written with high school level vocabulary at most.
Exponents and Logarithms can be first taught in Middle School in many places, but sometimes get revisited during Calculus in AP High School or at University level.

This one is easy. As we know from words like "photon" and "triumph", "pH" is actually pronounced "f".
I wanted to make that joke 😟
They told me at school that ‘p’ meant ‘negative log’. So ‘pH’ means ‘the negative log of the concentration of Hydrogen ions in moles/litre’.
pH 1 is 1 x 10^-1^ (strong acid)
pH 7 is 1 x 10^-7^ (neutral)
pH 14 is 1 x 10^-14^ (alkaline)
(Chemistry was a long time ago, though)
You're missing a 4 in the alkaline line
Thank you (4 now added!)
Isn't it Potential of Hydrogen?
That's what I was taught back in 6th Grade.
For what it's worth, my job is as an analytical chemist, dealing with pH readings every single day, and I've always thought this was correct.
Are We Smarter Than A 5th Grader?
Same for me
The funny thing is that I intellectually knew that there were plenty of non-English speaking scientists, but that knowledge was never considered.
Something like that. It's an incredibly weird term.
I assumed it was rho (ρ) of hydrogen since rho is used for density...

It stands for peeps mcgoo
It stands for "piled".
