Method Hydrogen Sulfide Method help

[Fire&Ash]

I'm able to find lime sulfur off Amazon. I can't really find hydrochloric acid. I think it's toilet bowl cleaner but the toilet bowl cleaners I see like Lysol idk what the percentage of HCL are. My questions are
1) what concentration of HCL do I need? I found 37% on Amazon
2) what products can I find on Amazon to get HCL?
3) do I need 150ml or 500ml each product to mix into hydrogen sulfide?

I already know the dangers of this method. I have an old beater in the back of the property that I will seal off with duct tape etc

 

[Intoxicated]

PPH 2022 suggests mixing 500 ml of lime sulfur with 500 ml of concentrated hydrochloric acid for a confined space like a car.

35 - 39% hydrochloric acid is generally considered concentrated. At so high concentrations, hydrochloric acid is a fuming liquid that actively releases gaseous hydrogen chloride, which is a highly corrosive and irritating gas.

The reason why concentrated acid is recommended is probably because it can react with lime sulfur more quickly than a dilute acid, thus producing H2S faster. A smaller time of exposure to low concentrations of H2S before reaching high concentrations of H2S (that effectively produce unconsciousness) implies smaller chances of experiencing some bad symptoms from inhaling the gas. But the presence of high amounts of hydrogen chloride released from concentrated hydrochloric acid into air may overweight the benefits of quick production of H2S due to discomfort caused by inhaling HCl. So whether concentrated hydrochoric acid is optimal for preparation of H2S is questionable.

It's also remarkable that whenever you open a vessel containing a concentrated hydrochloric acid after it was closed for a long time, a lot of pressurized hydrogen chloride is released immediately, forming a highly irritating cloud around. This is why I'd recommend to open containers with hydrochloric acid outside of the car or whatever confined space you're going to use.

The best techniques of H2S poisoning (causing the least discomfort) would use producing H2S by reactions like Al2S3 + H2O or Na2S + H2SO4 with further adminestering of the gas via a face mask or a plastic bag.

You may be better off doing iron sulfide with sulfuric acid. There won't be any Chlorine gas produced this way, so you'll not only have less suffering but also a lesser chance to attract attention (Chlorine's distinct color and smell is more likely to get people alarmed).

 

[lvkhan]

WHEN EXPOSED TO HYDROGEN SULFIDE:
o 0-50 ppm: minor eye, nose, and throat irritation
o 10-50 ppm: headache, dizziness, nausea/vomiting, coughing,
and difficulty breathing
o 50-200 ppm: severe eye and respiratory irritation, convulsions
and shock, coma, and even possible death
o Levels above 700 ppm will cause immediate death after just
two or three breaths.

Only ½ to 1 cup of each chemical will produce enough
gas to fill a standard four door sedan with 1000 ppm of
toxic gas. This is instant death !

As a person who works in a lab, be very very careful with concentrated HCl. The fumes alone are bad enough. Breathing them in will irritate your lungs (because it is slowly dissolving them) and you will get chemical burns if you get it on your skin. It will also slowly destroy any plastic so always store it in a glass container.

 

[Intoxicated]

You may be better off doing iron sulfide with sulfuric acid.

FeS + H2SO4 should be better, but the acid must be dilute (10 - 20%). If concentrated H2SO4 is used, irritating SO2 may be produced.

There won't be any Chlorine gas produced this way

HCl doesn't produce chlorine upon reacting with sulfides/polysulfides either.

so you'll not only have less suffering but also a lesser chance to attract attention (Chlorine's distinct color and smell is more likely to get people alarmed).

Attention may be attracted by H2S which has a distinct odor perceivable at very low concentrations.

WHEN EXPOSED TO HYDROGEN SULFIDE:
o 0-50 ppm: minor eye, nose, and throat irritation
o 10-50 ppm: headache, dizziness, nausea/vomiting, coughing,
and difficulty breathing
o 50-200 ppm: severe eye and respiratory irritation, convulsions
and shock, coma, and even possible death

Those effects take place after a long exposure (several minutes or hours, depending on the H2S concentration). The mechanism of irritation is likely to be related to oxidizing of H2S to SO2 in presence of atmospheric oxygen and moisture, eventually forming sulfurous acid. High concentrations of H2S (over 1000 ppm) cause rapid loss of consciousness before significant irritating effects, nausea or vomiting could be achieved. At 5000 ppm or above, unconsciousness appears shortly after a single deep inhale (probably within 10 seconds).

I was thinking I'd have to dilute the solution anyways since ferrous sulfate acts as a passivation layer in concentrated sulfuric acid (which is why you can store concentrated solutions in steel tanks, but not diluted)

It shows in this that when chemicals are mixed together it takes 9 minutes to produce a fatal amount. What would it be like in that time before death? id imagine the gas would be so painful that it would force you to leave your car before it reaches that fatal limit. I've heard this method be advertised as being painless am I wrong?

So I can't mix the two chemicals together in a bucket? It has to be glass?

If an attempt goes exactly like in that video, I think yeah it'll not be peaceful at all. But from the conversations I had with the user intoxicated, I heard that the reaction with polysulfides are worse and slower. The one pesticide used in the video is probably Lime Sulfur, which is mostly calcium polysulfides. So I believe if one knows what they're doing (knowledge in chemistry or so), they can choose a more efficient reaction than lime sulfur+toilet cleaner. (sodium sulfide, aluminium sulfide, iron sulfide etc.)

Another thing is one can choose an environment which has even less volume than of a car, so the PPM concentration goes up even quicker.

I think, most kinds of plastic should withstand concentrated hydrochloric acid for at least a day. For example, a noticeable damage to a PET plastic bottle occurs when it contains concentrated HCl for weeks.

Whether a plastic material is suitable for storing concentrated hydrochloric acid for a long time (months or years) depends on the type of plastic. Different kinds of plastic show different resistance to 37% HCl.

Examples of plastics that can be used for storing 37% hydrochloric acid for a long time at room temperature:

PTFE, PFA - very high chemical resistance to most acids, including concentrated HCl,
PVDF, ECTFE - excellent resistance to 37% HCl,
CPVC, HDPE - good resistance to 37% HCl,
PVC, UPVC, LDPE - satisfactory resistance to 37% HCl.

Examples of plastics that are not suitable for storing concentrated HCl for a long time: PET / PETE, polypropylene, polycarbonate.

If an attempt goes exactly like in that video, I think yeah it'll not be peaceful at all. But from the conversations I had with the user intoxicated, I heard that the reaction with polysulfides are worse and slower.

The reaction shown on the video doesn't look slow at all )) It's very intense, so the acid quickly escapes the bucket like boiling milk. I suspect that those massive acid spills on the seat release lots of gaseous hydrogen chloride instead of useful hydrogen sulfide, and this is a great example of how the reaction should not be carried out.

The disadvantage of using polysulfides is that the reaction produces lots of useless insoluble suflur that can significantly increase formation of foam which quickly grows in volume and escapes the vessel

2 CaS5 + 4 HCl = S8 + 2 CaCl2 + 2 H2S

Besides, the foam traps lots of H2S without releasing it into the surrounding atmosphere for some time.

Another thing is one can choose an environment which has even less volume than of a car, so the PPM concentration goes up even quicker.

Using a plastic bag is better, because a much smaller amount of H2S and a smaller amount of reagents used for producing it are needed to achieve a rapidly acting concentration of H2S, and you don't have to inhale toxic gases before the bag is sufficiently filled (that can be observed from a big safe distance).

Sorry I'm not chemist smart. Your saying the gas in the car being made from the bucket wasn't hydrogen sulfide? But hydrogen chloride?

Based on what I've seen there, it was likely hydrogen sulfide contaminated with a great portion of hydrogen chloride.

At 5000 ppm or above, unconsciousness appears shortly after a single deep inhale (probably within 10 seconds).

Can you please chat with me or message me to so I can understand this better? I looked at the PPH and they say to use "lime sulfure and hydrochloric acid" but your saying this will not produce good hydrogen sulfide?

 

[Intoxicated]

So it's not hydrogen sulfide?

If you repeat the procedure shown on the video above, you get hydrogen sulfide (produced in the reaction) mixed with hydrogen chloride (released from hydrochloric acid).

In that experiment, hydrogen sulfide was produced in amounts sufficient for causing loss of consciousness and death. Therefore CTB would be possible if someone were inside the car. But hydrogen chloride (which probably was also present in large amounts) is a potent irritant (much more strong irritant than H2S), and it can make the experience of inhaling the mixture of gases (H2S and HCl) significantly unpleasant.

rom what I understand hydrogen sulfide isn't painful. Thats why I chose it

would you be willing to have a conversation on this method? In the chat option "conversation." I rly want to see if this is doable for me.

This is my main method. I want to understand. If I pour the hydrochloric acid into a bucket and then add the lime sulfur outside my car then put the bucket into the car (500 ml of each) I should have no problem. Thank you!!

It's very fast. You may lose consciousness while carrying the bucket to the car. I believe it is necessary to protect yourself while doing the work.

If the mixture partially escapes the bucket, this may present a problem (because acid spills may cause some incoveniences). Many people seem to underestimate possible complications that may occur when large amounts (such as 0.5 L + 0.5 L) of actively reacting chemicals are mixed together quickly.

For doing manipulations that take 30 seconds or less, it's possible to just hold your breath. If the lungs are filled with air to their maximal capacity, it's very hard to inhale something else accidentally before at least some portion of air is exhaled. Prior hyperventilation before breath holding may significantly increase the time before strong urge to breathe occurs.

Wearing protective gloves would be quite desirable though.

As Intoxicated says, plastic is good for short-term use. Just do not store it long-term in plastic.
