Thanks. Yes as far as I'm aware it is not very easy to get benzene unless you can list a source. And was not suggesting I try the above method. I was simply asking if anyone knows of an alternative to it, precisely because it is dangerous.

I want a small amount of benzene. Obviously it is not easily purchasable, but sodium benzoate is. I have heard one way is to dry distil sodium benzoate and sodium hydroxide, but the though of dealing with molten sodium hydroxide at such high temperatures sounds too dangerous. Is there any other...

If I was to electrolyse a hot sodium chloride solution I'm pretty sure a copper electrode would react to make copper chloride. Whereas I would have used graphite electrodes if the solution was cold, this reaction should produce sodium chlorate which can obviously be quite reactive with organic...

Right, Thanks guys. So they would probably need that scroll wheel thing to be of any use. Thinking about it now, I have seen these things before.

As a gift I received 25 of these things (the previous owner not knowing what they were). They're aprox 34cm in legnth. The orange bit is closed and doesn't detach, so I can't find any uses for it. The writing on it above the calibration reads... Regardless of their use I will most likely be...

Yeah, I gave up. Thanks for your help guys!

You're, right the limescale remover is a bit too viscous. The only other solution I can think of is the method of outgassing proposed in this video: . Could the gelling agent in the limescale remover might prevent this? and although the perfume of the limescale remove would probably also get...

I'd imagine this would be a simple matter of bubbling it through water. It also could be worth noting that I don't need this to be a very strong concentration or very efficient. Although heating the solution might not release the HCl, do you think boiling it could work? I understand this...

As a home chemist I don't have access to Hydrochloric acid, however I did find some limescale remover that claimed to contain 6.75% HCl. This substance is blue and soapy. Any ideas on how I could isolate just the HCl? (Obviously dissolved in water)

This is ~ 100 grams and I'll be sure to do it outside.

Thanks for the quick reply! What kind of dangers are there when dealing with ammonium nitrate? and by Crystallization are you referring to Recrystallization as described here? http://en.wikipedia.org/wiki/Recrystallization_(chemistry ).

I've made up a solution of ammonium nitrate from an instant cold pack, however the solution I've made is slightly cloudy and a dull yellow color. I've put it through a coffee filter once but it hasn't really helped. Is there anyway to purify my solution?

Are there more joules in a bullet or a battery (in it's lifetime). I'm afraid I don't know bullet calibres but we can assume that we're talking about an AA Battery.

As a casual experiment I was seeing whether I could make hydrogen from sodium hydroxide, aluminium and water. Rather than buy sodium hydroxide or go through a load of cleaning products to find it, I thought it would be much more fun to produce it through electrolysis. I set it up, and the...
