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.

[-] StupidBrotherInLaw@lemmy.world 3 points 1 month ago

I really hope you're joking. It's written with high school level vocabulary at most.

[-] Speculater@lemmy.world 21 points 1 month ago

It appears that an individual's heuristic analytical mechanism is engendering a subversion of their affective response system, resulting in epistemic determinations that lack substantiation from the linguistic parameters prevalent within the upper two quartiles of the demographic distribution.

Thank you, Mr. Data.

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.

Explainexplainxkcd.com when?

[-] arken@lemmy.world 46 points 1 month ago

This one is easy. As we know from words like "photon" and "triumph", "pH" is actually pronounced "f".

[-] kralk@lemm.ee 2 points 1 month ago

I wanted to make that joke 😟

[-] Puttaneska@lemmy.world 35 points 1 month ago* (last edited 1 month ago)

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)

The xkcd breaks it down for us, basically we don't know because the person who coined the term never specified what it was. It's either: puissance, potens, or potenz. Which means potency in French, ~~Dutch~~ Danish and German, the three languages the scientists published in.

[-] Bumblefumble@lemm.ee 10 points 1 month ago

Dutch and Danish are not the same language. So yeah, the Danish scientist published in Danish, not Dutch.

[-] Speculater@lemmy.world 2 points 1 month ago

Oh shit, my bad lol.

[-] Dagwood222@lemm.ee 2 points 1 month ago

I was taught it meant 'potential' but that was 6th Grade in the US, so I guess it was all a lie.

[-] Puttaneska@lemmy.world 2 points 1 month ago

Thank you. I think the decades-old chemistry-class flashback distracted me from thoroughly absorbing the full post!

[-] nodiet@feddit.de 2 points 1 month ago

Can the term potency also be used to refer to the exponent in English? Because that is what is meant by the terms in the other languages and I haven't come across that usage of the word potency in English

[-] Speculater@lemmy.world 1 points 1 month ago

I think that's accurate, the exponent is what it's referring to, but the pedantic types are worried about what the p literally means.

[-] Wizard_Pope@lemmy.world 8 points 1 month ago

You're missing a 4 in the alkaline line

[-] Puttaneska@lemmy.world 8 points 1 month ago

Thank you (4 now added!)

[-] overload@sopuli.xyz 26 points 1 month ago

Isn't it Potential of Hydrogen?

[-] Dagwood222@lemm.ee 3 points 1 month ago

That's what I was taught back in 6th Grade.

[-] overload@sopuli.xyz 11 points 1 month ago

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?

The funny thing is that I intellectually knew that there were plenty of non-English speaking scientists, but that knowledge was never considered.

[-] assassin_aragorn@lemmy.world 2 points 1 month ago

Something like that. It's an incredibly weird term.

I assumed it was rho (ρ) of hydrogen since rho is used for density...

[-] LodeMike@lemmy.today 11 points 1 month ago
[-] p5yk0t1km1r4ge@lemmy.world 7 points 1 month ago

It stands for peeps mcgoo

[-] ChickenLadyLovesLife@lemmy.world 6 points 1 month ago

It stands for "piled".
