Synthesis NaClO3

This shows the synthesis of Sodium chlorate (NaClO3). A saturated solution of Sodium hydroxide (NaOH) is prepared. Hydrochloric Acid (HCl) reacts with Potassium permanganate (KMnO4) to form Chlorine gas (Cl2). The Chlorine gas is lead through a small tube into a hot saturated Sodium hydroxide solution to form 'table salt' or Sodium chloride (NaCl), Sodium chlorate (NaClO3) and water (H2O).

2KMnO4 + 16HCl =- 2MnCl2 + 2KCl + 8H2O + 5Cl2
3Cl2 + 6NaOH(aq) =- 5NaCl + NaClO3 + 3H2O

[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

[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! :)

[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.

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–

[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

[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.

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
