I did not say that he should have kept 0.5M nitric acid. H2SO4 is used at 98% concentration for nitroglycerin I believe. HNO3 can be 60%+. For say, making Ba(NO3)2, 30% HNO3 could easily be used. 60% could even react too quickly.
You actually use around 0.5M to 1M solution for this reaction it's a lot safer than 30% which is considered concentrated.
The very dangerous part is diluting the acid, this is a very exothermic process and usually you add acid to water not the other way round.
I never said anything about the safety.
No but you were being condescending and cynical. Something that certainly does not come across as constructive, nor does is it do any good for the content of any forum.
I do not know anyone who walks past dying people. (Unless there's a risk to their own life). I have been taught first aid in school. I have also learned some out of school.
I have tended to an epileptic person before on a busy tube platform, of which I had to walk half way across to get to them. Everyone was more concerned with getting to work on time and they though he was drunk so didn't want sick on their shoes! Not one of them gave a toss that some poor block was having a fit. Believe me there are a lot of people out there like that. They all looked at him is the most vulgar fashion, and then took offence when I asked them to get back, one of the tos*ers even argued with me saying, ?can?t you just drag him out of the way, the train is due any minute??. There really a lot of people that don?t care about anything but themselves, do not kid yourself, we live in the real world.
It's very good that you were taught something, and took the initiative to learn more, its very commendable.

1st "reason". Some guitars are sprayed with NC lacquer to make them shiny.
2nd "reason". Ahh! NC is used to fire bullets! It's an explosive! It's killed people! It's used in fireworks!
Ban Guitars! [/sarcasm]
The point I was making is that you cannot make these sorts of analogies and comparisons. In PyromaniaMan?s case you ticked him off for having conc acids, rhetorically accusing him of owning them solely for the manufacture of HE.
98% Sulphuric acid is the most concentrated it can get before you go into the realms of oleum. There is nothing special about it. It is not solely used for the manufacture of HE and it is not the only way to manufacture HE. You can use many concentrations much lower than 18.4M to make nitronium ions, and thus nitrate organic material. You do not need it to be that concentrated. The real question is why not have 98%, I?d be more worries if it was a very specific concentration, which does have only one or two uses. I have half a litre of D2O in the shed, and next to it is some Lithium Carbonate, it doesn?t mean I make H-b*mbs at the weekend though does it?
I say well done for using your brains PyromaniaMan. I would have liked to have asked some technical questions about the dosage, but it?s a shame he does not post here anymore. Instead there was a load of hype. There?s no need for it!
