Making Na

(1/3) > >>

acx01b:
NaOH has low melting point (324°C)

what about the electrolysis (with Pt electrodes)
of melted NaOH ?
is it easy (let's say 1A will give correct yields nearly 0.5mole per hour)

inert gaz is needed becose O2 reacts with melted Na formed...
what about using desoxygenated air (O2 --> CO2) for it ?

thanks for advices.

pyroflatus:
is it easy
It's difficult and inadvisable for the home chemist.
Without knowing you but having read a few of your posts, I think you either wouldn't succeed, or would hurt yourself.

Perhaps stick to something more forgiving than sodium until you get up to speed.

And this post should be in the Newbee forum.
And are you legally an adult?

Lestat:
Do not use Pt electrodes, too expensive and very little point. Copper electrodes work very well, with barely any noticeable attack on the metal by NaOH.

The formed Na has a tendency to form little balls which spit and crack at the melting temperature.

The answer is, to use a knife and an old spoon to dig the Na out of the NaOH as soon as it is formed and transfer it to a jar full of hexane or naptha for storage.

Bee sure to use eye protection, and wear gloves.
A car battery is quite sufficient to provide the electricity.

lol
 yes i am ty

i am gonna try with very low quantity (2-3 grams of NaOH) in a broken at the top flask, supplier of the flask says 500°C maximum so 350 should not be a problem

i know that if Na burns it will be dangerous so i am gonna wear what is needed (glasses, big clothes)

pyroflatus okey i am gonna hurt myself good for me i am stupid and i like try dangerous things...

the true is that my level in chemistry is not bad and i know that with very low quantities many reactions can be tried step by step without many danger.

last day i tried but i got f bad Amperage: like 0.05... with 15V

pyroflatus:
Oh well, if you're determined to do it. Good luck.

Sounds like you're using a 50mA rated power supply, or something with internal series resistance of 300 ohms. Molten NaOH should have quite low electrical resistance (but I couldn't find a figure quantifying this. Temptation may send me off to the 'lab' with multimeter in hand... but I did find that Downs cells that are used commercially to produce sodium from sodium chloride run several tens of thousands of amps of current.)

Like Lestat says, a car bettery would be your friend, as it'd supply a couple of hundred amps is need be.

Oh, and if you're already melting NaOH and have a multimeter, woudl you be so kind as to measure its resistance while molten?
