Help Hydrogen Sulfide route

[pthnrdnojvsc]

Are you planning a big suicide party for 100+ guests?

You seem to want to CTB in the most difficult way. If I planned to decompose 1 liter of formic acid for whatever reason, I'd mix the acids gradually for safety. I wouldn't do this for suicide though. Making 2 - 4 liters of CO should suffice for this purpose. Using citric acid + sulfuric acid seems the most appealing method for me because of the lowest risk of exposure to irritating fumes.

1. well enough hcn for me In a car . how would I make sodium cyanide or potassium cyanide safely.

1. well enough hcn for me In a car .

IDK what would mean "enough" in a car. From what I've read, effectively working concentrations of HCN are close to those for H₂S. ≥1000 ppm is a must, and ≥2000 ppm would be better. 500 - 600 ppm seem insufficient for quick fainting.

Reaching sufficiently high concentrations in a large confined space may take minutes depending on how much reagents you mix and how much you heat them. Prolonged exposure to concentrations that are insufficient for quick LOC may produce unpleasant symptoms.

Two possible reactions for making HCN are mentioned here

If you wanna experiment, good luck.

how would I make sodium cyanide or potassium cyanide safely.

Safely? No idea

Good luck finding the products. I tried. They banned lime sulfur in the US except to agricultural producers (good luck getting around it). I wanted this method so bad but it's not attainable.

Try veterinary products. I was able to purchase a lime sulfur dip on Chewy

I'm getting the sodium sulfied, I just need someone else to CTB with at this point, especially since I now don't have access to a car

Best of luck to you

well here it is, now just to get Sulfuric Acid which can be gotten from a lot of places easily

So my attempt at CTB with an exitbag and nitrogen was a complete bust, I've now stumbled upon the Hydrogen Sulfide method and it sounds pleasing enough if I'd be able to do it correct that it would only take 1 breath for me to instantly get knocked out and die, however the main issue is it's confusing AF and figuring out what you actually need to get in order to do it and then figuring out how to get it is even more of a struggle because it seems like most things you just can't buy in America. Curious if anyone has any knowledge and know how to solve these struggles, it may help even more people struggling to CTB, and of course gotta do this method far away from people and put up warning signs

It seems that almost all of the potential methods are much more complicated to obtain & carry out than first impressions would make them appear

That's heroic ) I guess, pure carbon dioxide would be way less unpleasant to inhale than the fumes of concentrated formic acid.

As for making H₂S, here are some reactions that can be carried out with common purchasable reagents

Na₂S + 2 H⁺ → H₂S↑ + 2 Na⁺
FeS + 2 H⁺ → H₂S↑ + Fe²⁺
ZnS + 2 H⁺ → H₂S↑ + Zn²⁺
CuS + 2 H⁺ → H₂S↑ + Cu²⁺
BaS + 2 H⁺ → H₂S↑ + Ba²⁺
WS₂ + 2 H₂O + H⁺ → 2 H₂S↑ + WO₂ + H⁺
2 Al + 3 S → Al₂S₃; Al₂S₃ + 6 H₂O → 3 H₂S↑ + 2 Al(OH)₃
Mg + S → MgS; MgS + 2 H₂O → H₂S↑ + Mg(OH)₂

Dilute HCl and H₂SO₄ can be used as proton (H⁺) donors, but reactions that produce water-insoluble salts (such as BaSO₄) should be avoided.

Hi, can I ask you something?

I don't know how much of each I should use.

I can get Na2s 60%min solid form 1kg + HCl 12% liquid 5Litre

But do you think is enough to make H2S lethal and to lose consciousness quickly inside my car?

Concentrations 1.4 - 2.8 g/m³ are enough for losing consciousness in a few seconds. The volume of a car is usually in the range 2.4 - 4.5 m³. So 12.6 g (0.37 mol) of H₂S dissipated in a car should almost certainly suffice for rapid LOC.

0.37 mol of H₂S needs 0.37 mol (28.9 g) of Na₂S and 2 * 0.37 mol (27.0 g) of HCl completely reacted with each other. 12% hydrochloric acid contains 126.9 g of HCl per liter, so 27 g of HCl corresponds to 0.213 L (213 ml) of such a solution.

It's difficult to tell how much H₂S exactly is produced after mixing X amount of Na₂S and Y amount of HCl and waiting for T amount of time. It's likely that at least 10% yield (from the theoretical maximum) would be produced within a minute. Therefore, I'd expect that 0.5 kg of ≥60% sodium sulfide and 2 L of hydrochloric acid should suffice for reasonably fast production of rapidly acting concentration of H₂S anyway.
