Any hardware store and most supermarkets will stock NaOH as 'Caustic Soda', 'Draino' etc. A quick Wikipedia search returns this:The reason you can't find Red Devil Lye is because some folks use it in illicit drug manufacture. It is a very common chemical to obtain in some parts of the country but most major chains no longer carry it.
It is especially suspicious that one would seek to manufacture a common compound like this at home or to request how to find it
You should be able to find it at a local scientific supply house. $12/lb last time I bought it. My supply house requires that I maintain an account... some minor paperwork is involved, however. Why don't you try the same?
Noted as 99.8% is what is mentioned on the side on most Australian brands, unless you get it in solution. Just note NaOH will naturally decompose with Air to NaHCO3 or Na2CO3 so ensure a air tight container (where possible)Wikipedia(not in format) said:Sodium Hydroxide, NaOH, Lye
Found At: Grocery Store
As: Drano, crystalline granular drain cleaner
i think here in the US, draino is likely to have other chemicals mixed in, like chlorine bleach.Any hardware store and most supermarkets will stock NaOH as 'Caustic Soda', 'Draino' etc. A quick Wikipedia search returns this:

Decompose?... I would think of it more as a synthesis reaction.Just note NaOH will naturally decompose with Air to NaHCO3 or Na2CO3

You may safely assume it is impossible.Is it possible to make NaOH at home?
:rofl: A 2.3-million-electron-volt particle accelerator in his parent's garage. Good analogy.You may safely assume it is impossible.
Well, Michio Kaku built his own particle accelerator in the garage, so word "impossible" is perhaps a little bit too strong. But it is definitely one of these things that seem much easier than they are.
If you can find calcium hydroxide and soda, for example, then you can make NaOH:Im doing an experiment that calls for NaoH, but i cannont find red devil lye (same thing).
Does anyone know a practicle way to make NaoH or what other names it could go by in stores?
I would use that method, with a 5 gallon bucket. A quarter inch thick would be your best bet. Too thin would not stop the ions from passing through, too thick and you waste too much energy pushing the ions through.You mix up the concrete as normal and pour it into a mold. A cardboard mold shaped to fit your container would be great. For example you can glue or caulk plastic strips on the inside of a bucket to make a channel, then the concrete plate slides in like a window slides down in a frame. The concrete plate should be thin, maybe 1/4 inch to 1/8 inch thick.
Allow the concrete to dry fully, then submerge the plate in water for... lets say a week or two. The immersion leeches out the salt trapped in the plate giving a very porous structure. This porous plate is an excellent barrier for electrolysis purposes.
I am not too sure on the granularity of the salt. It may need to be either very finely powdered, like dust, or perhaps ground a little finer than table salt. The resulting voids need to be big enough to make connecting channels. If the salt is too fine it will be trapped and isolated in the concrete, and if it is very course the voids will allow ions to just pass right through.
Then it would be smooth sailing from there...afterward I would perform a titration to find the exact pH of the solution however.In a custard cup, dissolve 1 teaspoon sal soda (washing soda, sodium carbonate) in 50 mL water. Heat slightly. Add slaked lime mixed with water. Stir. Chemical reaction produces sodium hydroxide and calcium carbonate. Filter. Clear liquid contents contains the sodium hydroxide (lye). The calcium carbonate is held back by the filter.
It's not possible for you to find Ca(OH)2 ?CaCO3 would have to be heated around 800 degrees(celcius) to get CaO. I doubt it's easy to do at home, you'd probably need some special equipment.
About electrolysis, why is this filter neccessary?
And could you please describe how to set up the neutralizing solution for chlorine?
