Autoionization and the reverse reaction are constantly happening in water, and when the reaction is happening at the same rate forward and backward the system is said to be “at dynamic equilibrium” (aka, stuff is happening, but there’s no net change)
In pure water, the equilibrium concentration of hydronium and hydroxide are equal, so it’s said to be neutral. At room temperature, that equilibrium concentration is approximately 1*10^-7 moles per liter, which gives a pH of 7 (since pH is defined as the negative log _10 of hydronium concentration)
Interestingly enough, in other solvents a neutral pH is going to be a different value. IIRC, ammonia has an autoionization constant of 10^-30, so a neutral pH would be 15
That’s why the meme works. It’s not because water autoionizes; it’s because water is amphoteric, meaning it can act as either a Brønsted-Lowry acid or BL base depending on what what it’s reacting with. Put water with ammonia, and water acts as an acid. Put water with acetic acid, and it acts as a base

Close, the standard IUPAC acid nomenclature would be “hydrohydroxic acid”
Ibn Al-Haytham be with you
Edit: and I suppose the traditional response would be “and Popper with you”

2·8 个月前We use Roll20 as a VTT, but we all run a zoom meeting at the same time because we live in different states and continents and it’s good to see their faces (and their kids and partners). Shrug It’s a pretty wide range of technology skills and preferences, so we went with the stuff people know best.

Don’t get me wrong, I love PF2 and I mostly actually play 5E with my friends on zoom (that bunch of Philistines), but I can’t be the only one obsessively finding niche games online like Into the Odd and Forbidden Lands and Frontier Scum and Inevitable and porting them into system-agnostic hex-flowers that could support Dark-Tower-esque realm crawling and West March-ish living worlds that I can never find anyone that wants to play and…
Do I have a problem? Am I out of touch? No, it’s the D&D players that are wrong
I don’t even ever get the physical withdrawals or any noticeable effects, regardless of how often I do or don’t drink it. So, since my partner really does need the coffee first thing in the morning and I’m making it anyway, I usually have a cup because I like the taste and ritual. But when she’s out of town or getting coffee elsewhere, I hardly ever have any caffeine.
The exception is when I was taking Adderall every day, I really did feel some effects from the caffeine, mostly potentiating the amphetamine. I do miss that aspect of being medicated
Made well I enjoy the taste, but it’s ever been good at keeping me awake or making me productive.
Same. I eventually figured out that this is likely a symptom of my adult ADHD, and I either need unhealthy amounts of coffee or something a little stronger

Truly a brand new sentence
Looked like it had just come back from the ethereal plane, its eyes were so wide
Well, yeah. If I got chased down and caught by a predator 4 times my size, I’d be a little wide-eyed, too.
You can tell that this wasn’t written by a parent. Parents know that the small child is already covered in jam, despite there being no jam at the BBQ
Not an expert in Eastern religions, but it looks more like Shinto or even Hindu than Buddhist.
Us old folks can’t do anything about being cringe most of the time, but we can be supportive and protective of our kids. I think you’d agree that that’s the bigger win here, so good job fellow parent.





I’ve said it before and I’ll say it again: in PF2, you can be any type of character you can imagine
