Corrosive to what ?


It's a matter of what material you want to attack. If it's glass then I'll go with
hydrofluoric acid and cesium hydroxide - both will attack glass easily.
If it's gold then aqua reqia or cyanides.

*Why* would they have:
Metallic Sodium
Bromine
White Phosphorus (this was not something to play with!)
Potassium Cyanide
Mercury Chloride
Arsenic
Thallium
in a pharymacy?? :o:D

Saerynide, that would seem strange for a pharmacy given how dangerous
those materials are. It's definitely suspicious. Are we dealing with a troll here ?

Potassium Cyanide? ThioCyanide maybe.

Anyone see a problem?

What the hell is more dangerous than HF? The KCN you ordered at the pharmacy? ( <--Sarcasm, in response to below. You can’t just order KCN, I agree, he's a troll.)Perhaps you don't understand. IF YOU SPILL IT, YOU WILL DIE.

MadHatter,

Though dont, but its quite possible places would sell them to a pharmacy.

Hang-Man,

KCN is not quite that toxic. If you get it on your skin you need to wash it off. Its only life threatening if it gets in a cut, or you injest it, or you add acid and breathe in the HCN. It did used to be just another lab chemical.

Conc HF on the other hand, if you spilt on you my understanding is the toxicity could well kill you.

KCN wouldn't be a bad way to go. Eating sodium metal, white P or Br on the other hand.......

Well, the pharmacys, does not handle these chemicals. But when I worked there, I've access to order chemicals from the biggest chem-company in Sweden, without questions & restrictions.

I have heard of pharmacies, in the past, selling compounds of arsenic and thallium, along with strychnine, and I think KCN, for use as poisons to kill rats and other vermin. Buyers had to sign poisons books. However, this has just about ended, due to the widespread availability of rat and other vermin poisons containing warfarin and other coumarone derivatives, or "1080" (sodium fluoroacetate), which are much more easily treated with antidotes if accidentally ingested.

An aside: sodium fluoroacetate is among the deadliest pesticides in use. It is not easily degraded and will poison animals that eat the corpses of poisoned animals. There is no accepted antidote for it. KCN is fairly benign by comparison.

Tha is why fluoroacetate is used in poison pellets, made of cereal and dyed green to avoid the attentions of birds, and often dropped by air, for the introduced Australian opossum here in New Zealand, where it is the number one pest, ravaging native forests. However, KCN or NaCN is still used in poison paste (apple jam) for quick kills at bait stations where it is desired to collect the opossum carcases for their skins. There must be an antidote for it, however, as I have heard of veterinary surgeons successfully treating (with an antidote, along with stomach pumping) dogs which had eaten fluoroacetate-poisoned opossums.

I did see a few links that mentioned treatment of fluoroacetate poisoning, but they all looked to be research endeavors. I know that my (1950s) references on fluoroacetic acid and derivatives say there's no antidote, in contrast with cyanides and acetylchloinesterase inhibitors, but it's not surprising that something could have been discovered in the last 50 years. Still, I saw many MSDS sheets that warned "there is no antidote," so I suspect that this is a fairly recent innovation.

Talking about poisons, when I was at vacation in Hungary I could buy 1 Kilo bags of a 60% NaF and 30% Sodiumdichromate mix with 10% of a other unknown nasty :D

Logically my dad would'nt let me buy it :P
(Not that I wanted it, I would wet my pants trying to open the casing, let alone carrying it back in the car to Holland :o )




Dutch pride world wide :P ;)

The term "aqua regalis" actually sounds oddly familiar to me. Whether it is called aqua regia or the former I would just like to ask a few questions about this mixture. I would like test this mixture on some mild steels. Basically I've had first hand experience with concentrated Nitric, and Sulphuric acid. I guess I'm just curious about experimenting with acids that burn through metals instantly. After experimenting with strong oxidizing acids I figured that acids that burn through metals were just from the movies.

I have been looking for detailed info on sodium fluoroacetate for a while can any of you point me towards some good resources (my interest was peaked when reading a novel where it mentioned it was was of the strongest poisons know to man:D )

Is it right,that Pb is not attacked by HF?I made KF from HF and K2CO3 and I want to get the solid salt from the solution.But it attacks glas because of thaces of HF and perhaps the KF reacts with the glas,too.
I thought I could make a dish from Pb to evaporate the water.Or are there other possibilities?

Both nickel and lead are impervous to KF because of passivation.



One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.

So you could cast a container out of lead or nickel and use that to store HF/KF?

@superacids....why not H2SO4 + another lewis acid like ZnCl2 or FeCl3 instead of SbF5 ? - SbF5 might be first choice in being a strong lewis acid, but i think ZnCl2 or FeCl3 might also work nicely.

Did anyone mention the pKa of Caro´s acid here(for comparison):P?....i was wondering whether it would make sense trying to calculate the super-acid-strength using pKa-Values of the H2SO4 and the lewis acid?! :o

Hello!

I suppose you won´t have acess to Lewis-Acids, so what are you going to do with the corrosive chemicals? When you want to corrode metal (writing on it) you can make a little bit of boric acid on it and heat it with a gas-Burner. For Glass is hydoflouric acid great, but its dangerous. Other metals or combinations of them (i`ve forgotten the word:(, e.g. woods.....)can be corroded with a little hot sodium hydroxid-Solution. When you want to burn letters in Messing (Zn+Cu), nitric acid is good.

Edit: SbF5 is very expensive.

What is the english php-code for writing letters low? [tief] [/tief] ist the german but it dont work...
