V119 Sodium on water part 2 - Natrium auf Wasser 2

[FudbalskiZavisnik]

we did this in chemistry :D

[aaahhhhaaaahhhh]

Hey where can you get pure sodium?

[KingDarkGamer]

@lobig

sorry, i am just to young for so chemikal things xD

i don't understand anything :P

i just wundered why it burns on the water :O?

[KingDarkGamer]

Wieso brennt das Natrium denn, wenn man es auf Wasser tut?

[loblig]

@KingDarkGamer i pardon but my german aint to good, but ill hope u understand anyway...

2 Na + H2O -> 2NAOH +H2 + heat

the heat that the reaction causes will ignite the H2 witch is highly explosive :P

[ErikaLovesAdam]

We used to do that in the high school lab all the time.

[xxXpitboyXxx]

wiso wuerds den so pink?

[olympicfan2]

@xxXpitboyXxx das liegt am indikator phenolphtalein

[donschmiddy]

@xxXpitboyXxx ist zwar schon n wenig her seit dem du es gefragt hast, das liegt am delokatisierten (pi)-Elektronensystem des phenolphtaleins welches im deprotonierten zustand eine bathochrome farbverschiebung hat und dementsprechend die deprotonierten alkoholat gruppen als auxochrome gruppe funktionieren und die ketogruppen als antiauxochrom wirken, sprich einen +M Effekt besitzen. Ich hoffe du meintest deine Frage auf den aspekt der farbigkeit und nicht auf die beobachtung der Farbe, if no sry

[xxXpitboyXxx]

@donschmiddy ich hab keine ahnung was du grade gesagt hast =P ich war seit der dritten klasse nicht mehr in einer deutschen schule. versuch mal in englisch.

[SlayerRecords]

Endlich ma gute grafik (auch in der zeitlupe)

Mag ich :D

[Ahlwwy]

i wish see any element test with NA

[Roxy1217Gurl]

sodium is generally less reactive than potassium and more reactive than lithium.... Sodium makes up about 2.6% by weight of the earths crust making it the sixth most abundant element overall =)

[ChrisC2I]

So let's try and make sense of that video :

2 Na + 2 H2O = 2 NaOH + H2 + Energy

2 H2 + O2 (from the air) = 2 H2O + Energy That's the flame

Now what reaction products give this magenta colour to the recipient ?

Nothing in the primary reactions is soloured.

[TheSunshine42]

diesen versuch konnten wir in der schule nicht durchführen, dieses video hat mir sehr geholfen die reaktion zu verstehen.Danke:)

[GulfLanderNoside]

y cant i post a comment?

[Frresh123]

fast wie ne kleine sonne :)

[aperez5243]

we did this in chemesty it was awesome their were sparks every where!

[Moomooyourmom]

SWEEEEEEEEEEEEEET

[xcraighebert]

Sodium is one of the more stable metals, but sodium is converted to sodium hydroxide once it contacts water. Which is why is causes a huge explosion.

[Piparkakkumauste]

We did that in the school. It was nice.

[RandoRoller]

I did it too. Big explosion!

[Amokalypsed]

we did this today at school :D

[DarkAshes27]

crazy how you can burn in water huh

[utubemusiccritic]

What causes this reaction to occur?

[conmanwebb]

in sodeum it only has like 1 or 2 valiance electrons in the outer level and when any of the alcali metals are put in water that causes them to lose one and it just reacts like that

[xXKentoXx]

does this produce sodium hydroxide?

[vukasin93]

actually,it reacts with the water IN ur skin and flash... :D i mean Na reacts whit everything that has H2O in it... :D <3 Na ftw

[vukasin93]

don't try this at home :D just for those who don't know never touch Na whit ur hands... it will react with ur skin... :D

[Asasinrock]

really bad vid! x'D =)

It`S borinG"! >:D

[xXKentoXx]

you're so childish.

[CocoChanelParis15]

chuuuuuuuuuuuuch

[mcr000nataly]

wow it's like i'm really big and watching galaxies collide in the universe.

[footballruler606]

i did this in school today, that peice is so tiny, ares was like 4 times that, it blew up and there was sodium within 5 feet of the beeker

[mhighin]

try putting fire in hydrogen....... pop!!!!

[Holylake1313]

I did this in school today..

I was hit the places, hand arm and ear by those small parts in the end..

[suggestion87]

i didn't know but actually you were right. natrium and water...and i just didn't know ANYTHING about it! pathetic...once more

[Individuell83]

lol we made it today in chemie class but in our experiment it flies from one side to the different very fast =)

[vanessaiz2cute]

Woah 0.o

[Parrafan4eva]

wat the hell....

how does dat work???????

[Dubanx]

The reason water(H20) is doesn't burn is because there are few elements more reactive then Hydrogen & Oxygen. If you add an element even more reactive then Hydrogen like sodium then the element will violently remove and replace the hydrogen molocules.

Pick up a bucket of water. Now pick up a bucket of air. Which wieghs more? Water because it's denser. Water actually has more oxygen then air so it reacts violently when it can react. It's just the Oxygen just isn't available to most materials.

[sinkoonsouth]

i think the pink color in the water may be due to electron solvation by the water

[potassiumperchlorate]

I am not talking about the collor of the water but I am talking about the collor of the flame, a sodium compound is ALWAYS producing a yellow flame. This flame is red.

[potassiumperchlorate]

Don't you know wat strontium is? hahaha do you know anything about chemistry? Just look on your table of Mendeljev. Sr is an silver-grey alkaline earth metal, but slightley less reactive than sodium.

[potassiumperchlorate]

are you sure it is sodium? it becouse of the red flamecollor it rather looks like potassium, or even strontium...

Na= yellow-orange

K= purple-red

Sr= deep red

[anandramanathan]

Why is the solution pink. NaOH & KOH are colorless

[potassiumperchlorate]

I think there is an acid-base indicator presented, in this case it should be fenolftaliene (FFT), it is just to show an alkaline solution is formed.

[CsharpGeekComposer]

Phenolpthalein (phpth), not felonftaliene (fft)

[CroatianRocket93]

maybe he added fenolftaliene in the water that turns pink when in contact with. alkaline solutions

[LoATS]

phenolphthalien, I think you mean.

[LoATS]

and by THAT i mean phenolphthalein.

[thomas242007]

whats strontium??

[vinegar1991]

it's one kind of element.

[NH4NO3CH3NO2]

i dare you to grab that when your hands are sweaty

[Kellysrevenge]

one of the better video's for showing the reaction of sodium with water.

excellent.

[bledin2]

Becouse in german is SODIUM(NATRIUM)

[lilletizz]

Same for the US...

[simpsonstewie]

why don't you say the modern name of natrium SODIUM

[Mew7191]

awsome..I heard about this in class but I really wanted to see it in action (seeing and hearinga bout it are 2 different things)

[LucyiX]

can i find a video that shows how to obtain pure sodium metal?

[Malaachi]

+5 keep up the good work.

[Damnitkal]

it was transforming into a ssj

[VideoJunkei]

The sodium melted into a ball from the heat just before it burst into flame. Cool!

[austria117]

Nett :D

[Awbbie]

It look like a spirit or somthing.

[TheBlobIsCool]

yup definitely potassium

[adammerlinsmith]

No. Potassium reactions make a violet flame - not the characteristic vibrant yellow of sodium - and happen a lot faster and more violently.

[devilsaints06]

oh and thats not sodium cause when sodium reacts with water it explodes... thats just other element used to make those fires that u light up to make different kind of fire (color)

[haske789]

its true. thats pottasium.

[adammerlinsmith]

Not necessarily. Sodium usually only explodes when there's a lot of it.

[devilsaints06]

well he didnt use alot in the vid did he?

[devilsaints06]

u losers u cant find sodium from nature. its made by combining other compounds and its very unstable thats why the united states and other countries dont use sodium for nuclear bombs

[adammerlinsmith]

"Books: hate reading"

It shows. Sodium isn't fissile - only certain isotopes of uranium and plutonium are fissile, and used in nuclear bombs. Hydrogen is also occasionally used if the goal is nuclear fusion, not fission.

Nuclear reactions are far more complex than a simple redox reaction like sodium in water.

[devilsaints06]

ok....

[vittodav2]

i don't understood..what's going on? is a chemical reaction?

[d4rk1nt3ll3ct]

NO ITS SORCERY

[ericmoss13]

yes

[oxcar162]

were con i find sodium?

ps: youre video rocks

[sweoli]

lol

[alucard1201]

how do u separate Na from NaCl(salt) can i get the sodium out of the salt to do this?

[BirdValiant]

It needs to be molten, then you can use electrolysis. Don't try it though.

[alucard1201]

=) i wont =) or will i?

[crosse0]

do it with a bigger piece next time.

[Lexaaa21]

=D wikid it turned d solvent purple

[adammerlinsmith]

There was an indicator in the water - phenolphthalein.

It turns pink in a base.

[jack6565]

ahha akili to the max

[KillerKabel]

LoLs... Natrium is in a soda... Isn't it?

[joshuas3521]

And, it turned purple bcuz of the phenolphthalein (turns pinkish when exposed to a base).

[berndpfe]

The reaction is as follows:

With presence of water (in solution, immediate dissipation) :

2 Na + 2 H2O -> 2 NaOH + H2^

(Sodium hydroxide)

strong exothermal (greater amounts of sodium explode immediately).

[freakshow67]

zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz­zzzzzzzzzzz

[berndpfe]

Sodium on water is a very violent reaction, ending up with a fiery violent reaction going on but steadily accelerating, and if near the end, the sodium - meanwhile melted to a liquid burning ball decreasing in size - has enough steam pressure and suddeny going over to the gas phase by exploding (= reaction runs very fast on the final point).

[briy123]

its not salt for the last time people its a metal, salt is sodium chloride its a completely different substance when people say that this has too much sodium in it its short for sodium chloride

[adammerlinsmith]

Usually sodium ions, actually.

[briy123]

yes sorry you are right it is the sodium in the salt. but still that is not salt. if you put that in your mouth... ouch.

[DNM35]

put a piece in your mouth and let it ignite with your saliva..neat trick to show your friends at parties...glowmouth!!

[BirdValiant]

I loved the slow motion spinning fireball of doom shot.

[signherex]

Na is completly different from NaCl

[Alastor308]

I can hardly believe that we eat that stuff with fries.

[devilskullsixtysix]

Hmm... this seems similar to the borning of a star and its death. It starts out hot, producing light and heat, then slowly cools down to where it becomes a white dwarf, then BOOM!

[MonokuroBooHokKan]

And if we get a bigger piece we might make a mini black hole :D

[N5BQH]

We had a chem teacher who showed us that the gas formed by sodium reacting with water is hydrogen gas. He did this by holding an inverted test tube filled with water with it's neck below the water level of a large container and pushing a small piece of sodium into the test tube to collect the gas.

He then tried the same thing with potassium for the hell of it.(using a stand and some long pliers). The test tube ended up stuck in the ceiling.

[Pimpministrator]

wo bekomme ich natruim her?

[stian1990]

it's an redox that produce Hydrogen , that it's flammable

[Netexperimente]

You find the explanation (in english too) on the homepage, shown at the end of the video!

Greetings

[vmelkon]

"It's not sodium, it's lithium, sodium burns yellow"

Nope, Lithium reacts very slowly.

The reactivity goes higher as you go from Lithium to Francium.

Lithium

Sodium

Potassium

Rubidium

Cesium (or Caesium)

Francium

and you are not likely to see Francium since it is very radioactive and not abundent.

[f1snextchamp]

It's not sodium, it's lithium, sodium burns yellow

[sg57]

Im guessing, this is what happens:

The water molecules break the bonds in hte sodium, thus releasing alot of energy, or atleast enough energy to make a small explosion to break the rest of the sodiums atomic bonds...

Im sure thats wrong, but please correct me. also, cant you obtain pure sodium by melting table salt in a metal pan, than running electricity through it? Where can i find electricity to run through it? A car battery, some electrode things, or what?

[phj1990]

Alkaline metals react with water to produce alkaline hydroxides and hydrogen gas, which is ignited by the produced heat.

Yes you can obtain sodium metal by electrolysing molten table salt. But I recommend you to not do that! Exceedingly toxic chlorine gas is evolved as well, your elektrodes will almost certainly react, and you're working with exceedingly high temperatures. In other words, it's exceedingly dangerous to attempt to produce alkaline metals.

[nitrex]

Not just that, you wont be able to produce enough, you need a lot of electricity and a huge place. So its mostly produced in lab factories.

[Dracowrath1]

wild....now I have to see that in reality, as in, right in front of me. the video of it was awesome, but it's gotta be much better to be there to see it instead of a recording

[nitrex]

Yes i have some of that, you can buy them online but you need to be a little familiar with the metal on purchase.
