How to make pure sodium? Answered

Is there anyway I can make pure sodium from salt or balking soda,and no I would not make a bomb with it.

You can make it with baking soda, marble, and magnesium or tinfoil. Put the baking soda and marble on a pan and put the pan in the oven for 2-4 hours at 200 degrees Fahrenheit. The baking soda is now sodium carbonate and the marble is now quicklime. Leave the sodium carbonate and put few drops of water on the marble. The marble should swell and crack.It has turned into calcium hydroxide. Now dissolve the calcium hydroxide in water and than dissolve the sodium carbonate in another container. Now slowly add the sodium carbonate solution to the calcium hydroxide solution until no more white stuff is formed (precipitate). Now filter the result. Leave the white stuff and let the liquid evaporate. The crystal that is formed is lye. Now weigh out 1 gram lye and 1 gram either finely powdered aluminum or powdered magnesium WARNING: ALUMINUM POWDER IS EXTREMELY DANGEROUS AND SHOULD NO BE USED UNLESS YOU HAVE WELDING GOGGLES BECAUSE IT GLOWS VERY BRIGHTLY WHEN LIT. Now mix the two powders well and than put the mixture in a cone shaped piece of tinfoil and light. If it does no light than try heating the mixture over a small fire. Now turn the black stuff into powder and than take 50 mil of mineral oil and pour it over 200 mil water and than prepare the container your going to store the sodium in by putting mineral oil in the container you plan to store the sodium in. Now drop the slag into the container with mineral oil on top of water. It should bubble and shiny pieces of sodium should float up to the top press them all together and than put the chunk into the container you filled with mineral oil to store. And BAM! you have sodium

If you search "sodium electrolysis", and go to images, multiple diagrams coem up showing liquid, or aqueous, NaCl with two electrodes in the solution connected to a battery. You could probably use a car battery, and you would jus need some sort of clay pot to hold the molten NaCl.

Also beware of the chlorine gas that is one of the products of the reaction (i.e. do this outside adn with really good ventilation)

For people who are freaking out about bombs here, there is a possibility that people saw the video I did where someone shows how to start a basic fire with sodium...For people who don't know much about chemistry and are interested in how to make a fire in a survivalist situation in a downpour with wet tinder, well, they might also decide to ask if sodium is the right thing for that, read further, decide that it is not and move on. That is what I did.

The easiest way to do it is not with salt. That's too much problem. F**K that. I am going to tell you what are you going to do. I am a Chemistry major. You will pass high current trough a pickle. Thats crazy ha! I thought the same thing. The pickle will emit a yellow light, which means that sodium is in excited state. Once the yellow glow is gone, you will open the pickle and there! grab the sodium and make a bomb.

Nothing like having somebody with less-than-zero knowledge of Chemistry and Physics trying to get all scientific-like with their "experiment-ing", is there..

Make Sodium ?!? Is he/she even aware that Sodium IS an element?

Obviously they mean isolate/purify some sodium from one of its compounds ~ but that's NOT what their subject-heading states..

And this then begs the obvious basic question: Why ???

Does he/she have some kind of death wish ??

I have years of experience with explosives and I can tell you that "experimenting" on a small scale is an immensely helpful teacher. After you burn your eyebrows off once, you are much more careful when handling potentially hazardous substances.
As for your comment about "making" an element, it is very common for people, even those with extensive scientific knowledge, to say they are going to "make" an element. It is implied that they are extracting it, not making it.
Finally, why is a good question, but not when it is asked in an ignorant manner. I have had chemistry courses where students were required to make elements from common household substances. Usually, these assignments were done on paper, but not always.
By reaming a student for scientific ignorance, you have displayed your own ignorance. Please keep it to yourself.

I have started a new year of school with chemistry biology and physics as my classes. So far we have learned about all the alkali metals. The chemical reaction that takes place can be described by this formula:
Na + H2O = NaO2 + H
So far almost everyone has "explained" that sodium reacts explosively with H2O (liquid water). This, however, is not true. Sodium, being an alkali metal, is reactive toward Oxygen not water. Not trying to patronize but if the end result includes Sodium being bonded with the Oxygen to make Sodium Oxide (Sodiums version of rust) and the hydrogen being left out, one could deduce that Na reacts with Oxygen not water. This also explains the comment about it corroding in air. This is why our school (who are not really allowed to have it anymore) store pure Sodium in paraffin oil or paraffin wax. And because our teacher is a cow (the mooing variety) we don't learn any of that sort of stuff. But you may be able to skip a step. In our practical lesson we boiled salt water to get table salt (NaCl) but the water (strangely enough) boiled and the salt went everywhere. Maybe if the salt were evaporated without boiling it, it could leave a sheet of salt which could be directly electrolised possibly. We haven't done much on that so I'm not sure if you can electrolise a solid or if it can be any state.

This is not true, the equation for this is a synthesis reaction, of a active metal and water is this for sodium: 2Na+2H20= H2 +2NaOH or sodium hydroxide

look no further :3

Salt or NaCl consists of :Sodium- the metal and Chlorine- and fortunately you can separate these but this is the only practical way of getting pure sodium metal

if you are able to melt the salt into a liquid and then run electricity through it you can break the salt down into sodium and chlorine so i would advise doing this in a well ventilated area as chlorine is a toxic gas

if you plan no making alot consider investing in making what is know as a Downs Cell

if you plan on making a little you could probably find a basic video on electrolysis on the internet just replace the solution with molten salt if you do this you should be good :3

Ok to make sodium metal just get some sodium hydroxide and magnesium powder and parrafin wax. You will also need a fuse for fireworks and a suitable crucibles to place the chems in. Then place a small amount of magnesium powder in the crucible. then on the pile of magnesium powder place a slightly larger amount of soudium hydroxide on it. Mix em together and place the fuse into the mixture. light the fuse and place the lid on the crucible. get a good distance from the crucible because the reaction is very violent. Once the reaction is done pour the wax in slowly while the mixture is on fire to control the sodium. Watch this video for better detail: http://www.youtube.com/watch?v=908rjHQ5mmc

Sodium Chloride is the way to go. You need to get your hands on a torch of some kind to melt it first so that the NaCl will conduct electricity (you can buy a soldering torch at any hardware store, mapp gas or oxy-acetylene is preferable). You don't need to melt the whole batch of salt, just enough so that you can stick your electrodes into a pool of it. If your using a high enough current, the rest of the salt will quickly melt. Then, if you want a decent amount of pure sodium, your gonna need a DC power supply with high amp capabilities (say around 50 amps; you can use any amperage that you want it will just take an eternity if it's low). You should find some graphite rods for your electrods. Finally, you need some inert gas like nitrogen, helium, argon, or another noble gas. When you remove the sodium that you have plated out on the graphite, it will immediately burn unless you immerse it in an inert gas. Once it has cooled, store it in kerosene.

Kerosene, or mineral oil, or something else hydrophobic. Otherwise the humidity in the air will get to the sodium surface and it will react. Not as strongly as lithium, but enough to be unpleasant.

Does it, kerosene also insulate high voltage (is it a more resistive then air?)

kelseymh (author)Sandisk1duo2009-01-05

This has nothing to do with insulation. Sodium is highly reactive with water. The kerosene, being hydrophobic (i.e., it doesn't mix with water) acts as a mechanical barrier to keep air, and its humidity, away from the sodium.

. I can't find a chart of "hydophobianess." Probably help if I knew what the property was called. heehee
. Searching for "sodium +kerosene" turns up a lot of hits, but I didn't see anything about why kerosene is used so often, instead of some other liquid.
. Searching for "sodium +gasoline" just turns up stuff about de-sulphuring gaso and Na contamination.

I typed in "hydrophobic" (the chemistry term I knew), and got a Wikipedia article. That revealed that the noun form is "hydrophobicity."

It appears that the quanitative
measure for solid hydrophobes is done via the "contact angle" (the angle which the surface of a water drop makes at the surface of the material). I also can't find a quantitative measure of hydrophobicity for liquids (oils), nor can I find a nice table of relative or absolute hydrophobicities.

Argh.

. Same. It would help if hydrophobicity were measured in something besides degrees. Searching for "centipoise chart" turns up a lot of good viscosity info. "hydrophobicity chart" fails miserably (unless you are dealing with amino acids).
