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.

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".

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)

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

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

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

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

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.

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