They want 6% which isn't inherently explosive or irritating. Usually this is readily available as per the 3%, you may need to 'shop around' to find a specific company/branch that stocks it however. Personally, if you are using it for your teeth I would find a brand suited for oral use (e.g. Hydrogen peroxide 6% BP) probably from the chemist If you must use 12%, I think there is a version that is 15% BP. Not sure how readily available it is- but it can easily be diluted to required concentrations.

I have interest in sodium as an organic chemist. Strong bases like sodium amide and alkoxides require sodium metal for any decent yeilds of the reagents. My idea is based on the mercury process for production of sodium hydroxide. I would be insterested in feedback as the method doesn't involve high temperatures or any reactive metals other than the produced sodium which I feel makes it safer (mercury is a much more predictable hazard than highly reactive metals exposed to who knows what at 1000+ degrees C). I am reluctant to go into detail as I havent had the chance (mercury is hard to come by) to test it and don't want anyone hurting or poisoning themselves trying to copy it. So just basically, the THEORY behind the method is to: Form the sodium in the mercury as per the mercury cell process for sodium hydroxide production. Collect the amalgam Remove mercury from the amalgam by vacuum leaving behind sodium metal The sodium would be contaminated with mercury- but seeing as im using this for reagents thats not so much of a problem as the mercury probs wouldn't react. I want to re-inforce that this is just an idea that I want feedback on, it may not work and it may be extremely dangerous particularly for amature chemists.
