@raceprouk What about the one that says that three days with relatives passes like three months? That's relativity for you.

Which one? There's three.
- Relativity may not injure a human being or, through inaction, allow a human being to come to harm.
- Relativity must obey orders given it by human beings except where such orders would conflict with the First Law.
- Relativity must protect its own existence as long as such protection does not conflict with the First or Second Law.

But lack of reality significantly harms a human being. Which makes following the Third Law an essential requirement for following the First Law.

The best part is that all of them consist of well known facts and no lies.
Last time I checked, chemicals are classified as acids if they have a pH level of less than 7. So no, it's not an acid.

Actually, the definition for acids and bases is largely independent on pH levels, dependant on which definition you're using. pH is a result, not a defining characteristic. It's also relative and can change. For instance, ammonia is usually considered a (weak) base. But if you let ammonia and sodium hydroxide (a strong base) react then ammonia is an acid in that specific reaction.
According to Brønsted and Lowry, an acid is a proton donor. H2O is very much capable of doing just that (it's the reason why neutral water has a pH of 7 in the first place!)
According to Lewis, an acid is a molecule capable of forming a covalent bond with an electron pair. Since Oxygen is very much electrophilic, it can do that just fine.
Basically (pardon the pun), the water molecule is amphoteric which means that it can act as both an acid and a base. And just to make it clear - this is not one of those Schrödinger's Cat situations. It actually is both.
So, the above label is true albeit incomplete. I would not mark it as wrong in a chemistry exam.

@anotherusername Are you saying that hydroxyl acid isn't an acid? It's right there in the name.

All materials with a pH are capable of doing it... pH just measures how willing they are, relative to other materials. Hence why this:

Is no surprise. pH is an equilibrium reaction. Take two compounds with different pHs and mix them, and they will react... in order to find a new point of equilibrium. The farther apart their pH values are to begin with, the more violent of a reaction you'll get.
Demonstrating that something that will react with a very strong base does not make it an acid in the general sense, though. The general sense is: pH lower than 7, acid; pH higher than 7, base; pH of exactly 7, neutral. Anything more complicated than that simply can't be stated in so few words.
@rhywden said in The Official Funny Stuff Thread™:

If you asked whether water was an acid or base and wanted to give full credit for "both"/"it depends" and partial credit for "neither", I could see that, but "acid" and "base" would both be wrong. And you'd just confuse students, if you weren't teaching college-level chemistry, where they're supposed to have already learned that it's not quite as simple as just comparing the pH to 7.
-
Listen, you are entitled to your opinion but what I detailed is actually what is taught both in school and in university.
pH does not define a base or an acid. That's what the pKA (and pKB, respectively) values are for - to determine for a particular reaction what compound will act as the base and which compound will act as an acid.
You're welcome to your layman's definition. But don't try to tell me either what to teach in school or how Chemistry defines the term.
You just spoke yourself of the pH level. Well, then pray tell, how do you arrive at a pH of 7 for water?
Neither Arrhenius, nor Brønsted/ Lowry, nor Lewis would disagree with "H2O is an acid with a pH of 7", save for probably wanting to add "at room temperature". Because the fun part? If you heat the water then you'll get an pH below 7.

I tend to call it either hydroxic acid or hydrogen hydride, depending what specific form of danger I want to imply. I think both are valid chemical names, but I'm sure @Rhywden can correct me if I'm wrong

I identify with the laundry ones.

Hydroxic acid is correct, Hydroxylic acid as well. Hydrogen hydride is not, as that would be a very weird compound being H-H- - i.e. a negatively charged Hydrogen molecule. That simply is not capable of existing ;)

According to the wiki article,
Using chemical nomenclature, various names for water are in common use within the scientific community. Some such names include hydrogen oxide, as well as an alkali name of hydrogen hydroxide, and several acid names such as hydric acid, hydroxic acid, hydroxyl acid, and hydroxilic acid. The term "hydroxyl acid" used in the original text is a non-standard name.[15][not in citation given]

I'd be surprised if someone recognized that but didn't recognize it before they saw the loop.

I was trying to figure out what that was there for. The request timed out.

ITYM hydrogen hydroxide. Hydrogen hydride would suggest a formula akin more to H2

@jaloopa Of course it is.

@zecc
break
is used too much, and can be ambiguous at first glance. We should replace it withgoto

The four compass directions are redundant, since they all fall through to
default
. Which would catchDirection.Sky
anyway.

I prefer to use the name hydronium hydroxide. ;) In part because you really don't get bare protons wandering around in solution…

@dkf If we want to get really then we'd also need to consider that we also don't have solitary hydronium ions wandering around and it's more like H9O4+ :D
