Water.  

Water looks at chemistry and roundhouse kicks it into quarks. Water does it’s own thing and doesn’t care about the rules scientists have made for other liquids and such.

For starters, looking at simply it’s composition. Water should be a gas. To example, take a look at ye ol’ table of chemistry.

All atoms have a mass. The upper left corner has the lightest atoms and they get heavier to further down and right you go. Molecules are a combination of atoms. And the more massive the molecule gets, the higher its boiling and melting point, aka more likely it’ll be a liquid or solid at room temperature. 

As you can see, with 2 Hydrogen and one oxygen atom, water (H2O) is a fairly light molecule (18 g/mol). Two similar molecules are Ammonia (NH3, 17 g/mol) and hydrogen sulfide (H2S 34g/mol ). 

But here’s the thing. NH3 and H2S are both gasses! Yet one is lighter and the other heavier than water. By this logic, water should be a gas to at room temperature. Which it clearly isn’t!

Speaking of melting points. Everybody knows ice floats in water right? Did you know that water is the only molecule which can float on its liquid form? It is! Butter does not float on itself, candles don’t float on liquid wax. But again, water doesn’t give a shit! And why does ice float? Because unlike LITERALLY EVERY LIQUID ON EARTH, water EXPANDS when it does from liquid to solid. And you’ll learn this first hand if you put a full bottle of water in the freezer overnight. That bottle will explode because the water expands upon freezing. Icebergs shouldn’t be possible!

Not only that, but water is deadly! Water in its purest form, will kill you if you drink it. The reason water is actually so healthy is that it’s full of minerals and salts we need to live. But pure water has none of this. And if you ingest it, it will leech these from you as you have more of it then this pure water and can even fill your cells with water (that’s osmosis baby) which will kill them, especially your brain cells. The most found liquid on the planet, in it’s purest form is deadly to you.

Luckily for us, you can’t find water in it’s purest form in nature. Because water is the best solvent and corrosive material on earth. It can dissolve anything and have it be detectable even at low levels. (Yes, this includes oil but as I said, low levels). Anything it touches gets dissolved. Even if it’s only reeeeeally small amounts. So technically each time you take a shower or go for a swim, you’re slowly getting dissolved! No other solvent or corrosive molecule is so versatile! 

Water is densest at 4 degrees celcius (39 fahrenheit) and not near freezing temperature. (Which is why lakes don’t freeze solid). It has INSANE surface tension, more so then most liquids. (hence why we even have an insect called a water strider). It freezes FASTER when warm then cold (No seriously, try this. Freeze a cup of warm water and one with cold and watch the warm water freeze faster).

In short, water as a liquid does not adhere to any rules but it’s own and that smug bastard knows it.

Yo hold up, water is a pretty cool molecule but it doesn’t break chemistry nearly as much as you think it does.

Let’s go over OP’s points real quick.

1) Water should be a gas because of it’s low molecular weight.

Not necessarily, while water does have a low molecular weight, it’s existence as a liquid is perfectly justified. The attraction between water molecules is much stronger than the other examples provided by OP, (i.e. NH3 and H2S)

(Molecular weight is actually a shit indicator for melting/boiling point sometimes but whatever)

Water has the capability for a type of Inter molecular force called “hydrogen bonding”: this is the interaction between the lone pair of an electronegative atom (NOF) with the bond of hydrogen with that of an electronegative atom (NOF). Its actually a lot more complicated than this, but I don’t think any of you care for me to explain the complexities of MO theory lol. so tldr, in order to make hydrogen bonds you need a donor (X-H bond, where X is N, O, or F typically) and an acceptor (lone pair on N, O, or F typically).

image

As you can see, H2O and NH3 meet these requirements, so they both have access to hydrogen bonding, but H2S does not. However, H2O has 2 hydrogen bond donors (2 OH bonds) and 2 acceptors (2 lone pairs) so it can both “donate” 2 hydrogen bonds to other molecules, and “accept” 2 hydrogen bonds. However, NH3 only has one lone pair, so it can only accept 1 hydrogen bond from other NH3 molecules. Thus, H2O will have more hydrogen bonds between itself and other H2O molecules, whereas NH3 will have less interactions. Thus, NH3 is a gas at room temperature, whereas H2O is not.

image

This is not exactly a “be all end all” rule though, since HF, which can also hydrogen bond, has a boiling point of around 19.5C (~67F for you heathens) meaning in a chilly room, HF is also a liquid, so this property isn’t exactly special for water.

Also like, LiH has a lower MW than H2O or HF and its a fucking solid, chemistry is kinda fucked that way.

2) Water is the only molecule to have a liquid phase more dense than its solid phase

Ok, this is actually a cool property of water, and in fact its one of the reasons there is life on earth. If ice were more dense than water, when lakes or rivers or anything froze, it would sink to the bottom, continuing to freeze until the entire lake was frozen bottom up, nothing would survive,

But this property is not unique to water.

Silicon, gallium, germanium, bismuth, and plutonium all have liquid phases that are more dense than the solid phase. This is because the crystal structure of these materials are more spaced out int he solid form then the atoms/molecules would be if they were a liquid.

3) Water is deadly, drinking pure water will kill you

Yeah, this is just osmosis being a bitch. But like, there’s way cooler stuff that will kill you if you drink it.

If you drink pure water, the cells would be more concentrated than the thing you’re drinking, so to equalize that concentration gradient, the water would either 1) flow into your cells via osmosis, like how you get wrinkly after being in the pool or 2) leech minerals and other solutes to equalize the concetration. It probably wont kill you? but you would probably have some mineral deficiencies

4) Water dissolves everything to some extent

This is true of most solvents. I could dump a chunk of metal in something like liquid ammonia, or acetone, and I could say that the metal dissolves a little bit into each of these. Smell paint thinner or alcohol or anything at all? the aroma compounds are “dissolving” into the air. Not exactly special.

image

(some metals actually dissolve in liquid ammonia look it up its very cool).

Ok, rant is over, and a lot of you are probably a little disappointed. So I will do my best to show you how fucked up molecules are.

You wanna see some fucked up molecules? Look at fucking diborane.

“hydrogen makes only one bond” my ass

Look at pentazole.

People managed to put 5 fucking nitrogens in a ring, and yet I can’t get up before noon on some days.

Look at this fucking monstrosity.

image

You’re not hallucinating. That’s a quintuple bond between the chromium atoms.
A Quintuple. Fucking. Bond. And your chemistry teacher had the audacity to yell at you for drawing more than 3.

TLDR: Water is not fucked. Chemistry as a whole is fucked.

Ngl I am at the brink of tears trying to look at those last three freaks and I really hope I don’t have to come into contact with any of them ever even tho I want to do a chemistry degree after I finish a levels.

king im so sorry. Boron and aluminum pull that shit like all the time. And aluminum also fucks with carbon and halogens

image

(B4H10)

image

(Al2(CH3)6)

Hell halogens do it to themselves sometimes

image

(I2Cl6, iodine has square planar geometry)

Also for your own sanity don’t look up some of the polyhalogen or polysulfide ions. That shit will fuck you up

One correction– the wrinkling of the fingers in water has absolutely nothing to do with osmosis. They’re not actually sure WHAT it is, but it’s an involuntary response by the body. The “skin has soaked up water” idea was actually disproved in the 1930s, when they discovered that if all of the nerves to a finger are severed, the finger won’t wrinkle. (The actual cause is constricting blood vessels.) Unfortunately, since the skin DOES soak up water, and this is something that is patently obvious and presents itself at the same time as the wrinkling, people continue to assume that correlation equals causation.

The current theory was that it is some sort of legacy-amphibian trait designed to give the fingers more traction in wet environs. This, while making a lot of sense, is not a slam-dunk– some experiments have concluded that it does improve the ability to handle wet objects (but not dry ones), but others have concluded that it offers no additional traction.

theres too many pokemon games where you play as a kid whos full of life and full of potential. there needs to be a pokemon game where you play as a college dropout who lives in a shitty apartment

astraldemise

your starter pokemon are trubbish, rattata and glameow. which symbolise the trash you keep forgetting to take out, the rats living in your walls and the stray cat you keep trying to befriend but it keeps hissing at you.

you guys dont get it its not supposed to be dark and edgy its supposed to be living in a mundane setting and slowly rediscovering the wonder in the world by going on a journey with a magical trash bag that is your friend, its about love and recovery and coping with the stress of your adult life with your friend who is made of sentient garbage
