Reaction of Sodium with Chlorine (subtitled)

[kennylau2010]

2Na+2H2O=H2+2NaOH, H2+2Cl=2HCl

[kmncztms]

hmm, table salt is produced, right?

[bearedman8]

@kmncztms That's a product of a Na+Cl=NaCl reaction, but I think the main thing here was: 2 Na +  2 H2O= H2 + 2 NaOH. The H2 is then ignited which also ignites the Cl. Naturally, an amount of NaCl is also produced.

[b43e65f77]

But if you don't drop water on it , the reaction will not happen?

[bearedman8]

@b43e65f77 I think it's more like a reaction of iron in oxygen, just metal rusting. It's slower and quite different from what you see.

[hexyournightmare]

try to suck up that gas in your lungs =)))

[neogastropoda1]

lol its a bong

[oomblikkies]

I am surprised that this reaction occurs without water, not because the sodium does not react with chlorine (it react very well), but the clorine reacts with the surface of the sodium and forms a protective layer of sodium chloride.

[1234567eboy]

cool how did you do that

[yes4me]

wow...

[ManlySlut]

why must you add water?

[dukcaboose]

sodium..(Na) (Alkali metal) reacts to the water compound.....in the form of a combustion reaction...

or something like that...

[astronoman11]

@dukcaboose no it doesnt

[maxyevs]

reaction between sodium and chloride is just a bit too much activation energy to be spontaneous... replacing hydrogen in water actually takes less energy

[jamies41]

to start the reaction

[Alin19862007]

I remember doing this experiment in highschool,but I didn't add water, I just let the sodium stay in the chloride environment,and in about an hour or so, the sodium has turned into salt (NaCl)

[aieoneoneeight]

You have chlorine in your high school!?

[CapitanoGUC]

i know that with magnesium, sulfur, kaliumpermanganat or so a,d some sort of oil - that way i burnde the kitchen table at chrismas eve with my brand new chemistry kid ...:)

[wattapassa]

hahaha potassium permanganate is an oxidizer, sulfur burns, magnesium burns at high temperatures... i know where this leads xD

[Flamester09]

lightbulb lol

[thomas242007]

thanks now we can make a chlorine bomb

[tarik221]

hi eveyone, i was wondering if anyone could tell me the theory behind this experiment! thank you! and please help!

[marcogt1240]

sodium Na and chlorine Cl form NaCl, common salt

anyway to react we need sodium in the form of hydroxide NaOH. Putting sodium in water make you to obtain

Na+H2O --> NaOH + H

so right now sodium is in the form to react. Reaction is esothermic (frees thermal energy)

[parasietje]

Wrong and right at the same time. Yes, this is the initial reaction. However, what really happens is the following:

2 Na + 2 H2O -> 2 NaOH + H2

This produces heat, and melts the sodium. This is the small flame you see. This provides the initiation heat for the following reaction:

Na(liq) + Cl -> NaCl

This reaction is very exothermic; it is an ion bond. This is the bright flash that is observed.

[PauliusChemLT]

Hahaha. You're wrond too ;D

Reaction between chlorine and sodium is like that:

2 Na + Cl2 -> 2 NaCl

chlorine is diatomic gas Cl-Cl

[astronoman11]

@parasietje try and go back to class and study that again ok? Your logic is flawed

[Borgfan]

Instant poisonous gas.

: (

[midguardz]

ok this is weird because sodium hypochlorite is a bleach used in washing clothes that has water flushing in my washing machine I'm surprised my socks don't explode or at least sand pours out of them. Maybe a different chlorine or sodium but salt is salt so I'm confused here. Please explain.

[videologger123]

Sodium hypochlorite is a bleaching liquid that is commonly diluted in water and sold under the brand name Chlorox. Sodium hypochlorite is a compound that possesses an entirely different set of characteristics compared to pure sodium and chlorine gas.

[videologger123]

Take water and hydrogen for example. Hydrogen is a highly reactive (explosive) gas and oxygen supports combustion. Water-H2O is the first thing you look for when there is a fire. Elements lose their individual characteristics when it forms compounds.

[videologger123]

Enough said... It's like getting married...

[life9118]

cool!

[8thgraderep]

WOAH THATWAS SWEET whered ya get chlorine from?

[bountykokos]

Mix HCl and KMnO4 (potassium permanganate). HCl you can buy in every technical store. For KMnO4 you can ask in Farmacy. (these information are for Slovenia, I don't know how it is in Panama.)

[kurohyou64]

you can mix ammonia and clorox

[8thgraderep]

serious?

[kurohyou64]

yeah. I heard it on jeopardy and I don't think they would lie... I don't recommend It though the lady almost killed herself.

[adammerlinsmith]

Baaaad idea. That makes mustard gas.

[Aquaria]

Poisonous gas yes, but not mustard gas, which is a sulfide, while ammonia and chlorine bleach don't contain sulfides. But teargas--Yeah, that's one of the possible reactions, since mixing ammonia and bleach can produce trichloramine, which has been used as a teargas. Hydrazine is another possible ammonia-bleach reaction. Either way, hydrazine and trichloramine are extremely volatile, and definitely not friendly to humans.

[adammerlinsmith]

Yeah, I corrected myself later. Or, at least, I think I did.

[adammerlinsmith]

Well, it depends on what kind of bleach, but generally speaking, you don't want to mix ammonia and bleach.

[kurohyou64]

yeah the person almost killed herself.

[Aquaria]

You can also get chlorine gas through electrolysis of brine (saltwater). Not a lot, but some. Basic chemistry. Would NOT recommend trying it at home. Chlorine is an extremely toxic gas.

[Dactacomplex]

wow.... NaCl..... is formed.... that's an impresive way of making salt.!

[remnant92]

omg u suck~ NaCl is salt~ and what they did here is the put Na to a Cl(g) (g) stands for "gas" lol

[Streifengetier]

lol remnant, u didn't understand anything... NaCl is FORMED he said and that's RIGHT, it IS an interesting way to produce salt

[AbsintheRTP]

Now imagine this to a big scale , ohoh, I love chemistry
