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 9 points 10 months ago

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

[-] Speculater@lemmy.world 22 points 10 months 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.

We’ve become exceedingly efficient at it.

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 10 months ago

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

[-] Speculater@lemmy.world 2 points 10 months ago

Oh shit, my bad lol.

[-] Dagwood222@lemm.ee 3 points 10 months ago

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

[-] nodiet@feddit.de 2 points 10 months 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 10 months 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.

[-] Puttaneska@lemmy.world 2 points 10 months ago

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

[-] Wizard_Pope@lemmy.world 8 points 10 months ago

You're missing a 4 in the alkaline line

[-] Puttaneska@lemmy.world 8 points 10 months ago

Thank you (4 now added!)

[-] overload@sopuli.xyz 24 points 10 months ago

Isn't it Potential of Hydrogen?

[-] Dagwood222@lemm.ee 3 points 10 months ago

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

[-] overload@sopuli.xyz 11 points 10 months 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.

[-] Dagwood222@lemm.ee 4 points 10 months ago

Are We Smarter Than A 5th Grader?

[-] callcc@lemmy.world 2 points 10 months ago
[-] Dagwood222@lemm.ee 1 points 10 months ago

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 10 months ago

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

[-] RememberTheEnding 14 points 10 months ago

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

[-] p5yk0t1km1r4ge@lemmy.world 7 points 10 months ago

It stands for peeps mcgoo

[-] ChickenLadyLovesLife@lemmy.world 5 points 10 months ago

It stands for "piled".
