Synthesis NaClO3

[ReapingMiner]

Higher temperature would help. IIRC you need atleast 60C for sodium hypochlorite to disproportionate into Cl- and ClO3, even then the warmer the better.

Cl2 + 2OH– → ClO– + Cl– + H2O

3ClO– → 2Cl– + ClO3–

[Oinikis]

i know the better way. make satured soliution of NaCl(for NaClO3) or KCl (for KClo3. heat the soliution (near boiling) and insert two carbon electrodes, and do electrolysis:

NaCl + 3H2O = NaClO3 + 3H2. if the soliution wont be heated it will make hypochlorite (NaClO) or if electrodes will be too far away it will make chlorine gas out and will create Hydroxide.

[Colt136]

im not dissing you or anyhting but this seems really ghetto and unsafe.

[mV33rs]

@MrGoldenmovies haha ja :)

[toothpick93]

if you new how much Sodium Chlorate you actually made you could of dissolved it in mroe water till its completly a solution again, then poor KCl into it, Potassium CHlorate would precipitate out + cooling will add to yield of Potassium Chlorate

[TerminalRhinoVirus]

So why does the Cl2 dissolve into the hot NaOH solution?

I thought gasses were more soluble in a cold solution.

this video is awesome

[Mr71seventyone1]

how to make naclo3 crystils sir help me out

[panomari]

How Many KMnO4 in bottle?

[crapbag1997]

see if i was doing this to make sodium chlorate for fireworks i wouldn't bother i would just use the kmno4 one of my favourite oxidisers

[mV33rs]

@crapbag1997 yet one of the most dangerous ones lol

[crapbag1997]

@mV33rs yea but theres nothing like a bit of danger to keep you on your toes

[diegonikki]

@mV33rs yep i hate kmno4 it makes very dangerous flash powders cuz i can buy from any drug store my excuse is my freshwater aquarium is plagued with fish tuberculosis and then they'll make u sign then they'll give u some

[mV33rs]

@diegonikki I somehow with an excuse made them give me KClO4 haha, I bought the whole jar! :)

[UTubeisSHIT523441]

You didn't react it enough. You should stop when there is no more bubbles forming. Also next time, I would suggest you transfer the mixture to the larger glass pot and add water, so the solution get less saturated and you can see a little better.

[guidocreusen]

dear sir,

you are genius =D

could i use another Cl2 source? i have KMnO4 but its quite expensive here

@xxtntrowyoxx do your homework, musterd gas is not Cl2

[mV33rs]

@guidocreusen I'm not sure so dont take my word on it, perhaps you can also use MnO instead of KMnO4. Another way is to mix Hydrogen Chloride with Sodium Hopochlorite. So ammonia and bleach. Not sure how well this works.

[NOBOX7]

@guidocreusen you can build a simple salt cell chlorine generater

[guidocreusen]

@NOBOX7 ok thanks. i found that electrolysing hydrochloric acid also works well.

[NOBOX7]

@guidocreusen this is a very good idea by the way, if you circulate the gas you could do this without haven the hole block thinkn your cookn meth, thanks vor posting this vid

[diegonikki]

try mixing calcium hypochlorite and sugar then add water place in metal or plastic bottle with hose on top i i usually use that for chlorine bombs but idk if the gas is pure or what

[xxtntrowyoxx]

so all u did was make musterd gas JUSt mix windex and bleach

[ExothermicVideos]

Even though it didn't go well it was still a nice video.

How can you tell that there was a lot of unchanged NaOH, by the viscosity?

[fortuneplant1]

Could I separate the potassium/sodium chlorate by evaporation?

[carambatsr]

How did you separate the salt from the sodium chlorate?

[mV33rs]

@carambatsr I didnt because at that time I had no clue. I found out later though. You can use potassium chloride to exchange its potassium ions with the sodium from the sodium chlorate. Potassium Chlorate is less soluble. 

[carambatsr]

@mV33rs Been there, done that with potassium chloride. I want the pure sodium chlorate. Apparantly sodium chlorate is tough to separate from sodium chloride in solution. It is an interesting challenge. Looking for practical suggestions.

[Tinsletooth]

Could some one explain to a stupid person (me) what is going on here adn dont use all of the chemistry turms. I want to make one

[61slugbug]

Do they sell SOLID pool chlorine in the Netherlands? If so, you might want to try a product called SCORCH ® (Calcium Hypochlorite). Order from an American company if necessary. (they might not sell SCORCH ® in the Netherlands, i don't know, because i reside in the United States). Just look for the words "Calcium Hypochlorite" on the package. It produces chlorine more prolifically and faster.

[mV33rs]

@61slugbug I'll try to find that, im currently experimenting with boiling a hypochlorite containing solution so it forms a ClO3 ion. 

[giuliodice1]

NaClO3 è un'ottima fonte di ossigeno,il quale si decompone:

2NaClO3---->2NaCl+3O2.

La decomposizione avviene quando il composto fonde.

[mandydandy123]

umm your equation isn't right.. I dont think you balance it ...the equation isn't right.. try takin some chemisty classes... might help

[mV33rs]

@mandydandy123 oops ur right lemme change it ;)

[arkfussion]

nice synth. also the swimming pool chemical calcuim hypoclorite reacts with acids to make Cl gas.

[ForunkePyro]

Another Question:

Does this also work with Potassiumhydroxide to form KClO3 ?

I have here like 1 kg of KOH...

[ytmachx]

@ForunkePyro Yes, it does!

[adriiPortillo]

shouldn't you be... hmmm AWAY from the chlorine ?? XD

[ForunkePyro]

Isn't this the right reaction? 3 Cl2 + 6 NaOH --> 2 NaClO3 + 4 NaCl + 3 H2 .... please correct me if I'm wrong....

[mV33rs]

@ForunkePyro I wouldnt know to be honest but I did not observe any gas forming in the reaction.

[ForunkePyro]

@mV33rs ...I was just wondering why only one NaClO3 is formed... The H2 could just bubble out with the leftover Cl2.... but I'm not sure...

[mV33rs]

@mV33rs I'll try to ignite it next time XD

[ForunkePyro]

@mV33rs good idea ;) ... I'll try this synthesis too... but to form the Cl2 I'll elektrolyse some NaCl in a beaker and catch the Cl2 with a glasspipe or sth else....

[mV33rs]

@ForunkePyro It would probably be hard to use electrolysis because you need lots of chlorine to have all the NaOH react.

[ForunkePyro]

@mV33rs Hmm yeah... do you know another cheap reaction that forms more Cl2? Potassiumpermanganate and Hydrochloric acid is very difficult to get where I live... Maybe some Pool-chlorine in water... the TCCS should react to HOCl and this forms HCl and HClO3 which forms Cl2, ClO2 and HClO4... but I don't know how much chlorine would be produced...

[adriiPortillo]

Use hydrochloric acid + calcium hypoclorite, it will also generate chlorine.

[mewrox99]

@ForunkePyro

Managanese Dioxide you can buy from pottery stores or get from battres will give cl2 from hcl

[ForunkePyro]

@mewrox99 I'll try that, thx! :)

[giuliodice1]

@ForunkePyro Consiglio anche questo metodo: Mettere in una provetta del cloruro di sodio e dell'acqua ossigenata,fare un bagno maria bollente ed fare l'elettrolisi con un filo di platino messo in un filo con del rame messo il più basso possibile nella provetta ed un altro di grafite sopra.

Si dovrebbe avere una resa del 90% di clorato di sodio perchè il cloro si ossida in acido clorico ed il sodio in idrossido.

L'unico inconveniente è che un po di ossigeno si disperda.

[panzuman]

doesnt alcohol and the chlorine tabs make cl gas? i know that because it is exothermic you also evaporate some of the alcohol

[dudomaniac]

You should do the reaction with near boiling sodium hydroxide solution and use more chlorine than stoichiometrically calculated. Please note that chlorine does not dissolve in boiling water, so you probably will need to find a way to make the bubbles smaller. This will also improve the reaction, as there will be a bigger reaction surface. Finally, a fermentor style reactor will improve the reaction even more, as this provides the highest possible surface for the reaction to progress.

[dudomaniac]

@dudomaniac A fermentor style reactor for this reaction would feature a submerged gas inlet, a stirrer and one or two heating elements with temperature probe. A gas outlet would be recommended too, so you can get rid of the exess chlorine by making a complex with urea.
