The solar system is broken

In one afternoon, the writer dissolved, purified and hydrolyzed nearly fifty kilograms of brine salt.

Seven or eight sealed jars of mixed acid solution were obtained.

The most abundant ones are hydrochloric acid and sulfuric acid, as well as some bromide and table salt.

However, the concentration of these impurities is not too high and will not affect the entire reaction process.

You have to ask the writer what to do.

That naturally creates a highly toxic air, hs hydrogen sulfide.

How toxic it is. Modern science shows that when its concentration reaches 0.012‰, it will cause acute poisoning in humans.

It can cause convulsions, palpitations, or even coma within seconds.

After a few mouthfuls, you will ascend to the fairyland. This process only takes three seconds.

However, this gas has a disadvantage, that is, it smells like eggs and is easy to detect. Of course, only those with fast hands will have a chance. After all, if you are slower, your central nervous system will be paralyzed and you will not be noticed.

Another problem is that hydrogen sulfide is heavier than air, so it usually settles on the ground and is fine if you stand there.

There was once a real case of a team heading to a volcanic cone for a scientific investigation. A fellow traveler had his shoelaces untied and squatted down to tie them.

But after several minutes, the man didn't stand up.

When someone moved him, the man was still tying his shoes, but he was already dead.

It turns out that natural concentrated sulfuric acid will be formed in the natural lake of the volcanic cone. Under the action of microorganisms, the strong acid will decompose and undergo complex reactions to obtain hydrogen sulfide, a deadly gas.

The main reason why the writer chose this thing is that the Wrangler's vitality is too strong, and he is afraid that it will not die in a short time.

Looking at these sour things, the writer fell into deep thought.

How to check?

The writer took one look at his iron shackles and his thoughts became vivid.

Gently pour the water from the earthen pot and pour a little onto the shackles. The iron shackles made a small gap with a sizzling sound.

"It's done."

Hcl is present and hydrogen ions are present.

Next is the sulfide.

In fact, sulfides are easy to obtain, but most sulfides are highly toxic and are dangerous to make.

After all, this thing is too poisonous. In the absence of standard glassware, the writer dare not choose casually.

But what? It’s not difficult,

"Xiao Li", the writer waved his hand.

It is a simple gas mask.

A rubber mask that conforms to the face and has no eye protection is not needed due to the precipitation of hydrogen sulfide.

The size of the mask can only protect the mouth and nose. There is a corrugated hose (animal intestine), and the hose is connected to a bamboo filter tank filled with granular activated carbon. There is an outlet valve at the front of the mask, and the exhaled air

Exhaust from here.

At the bottom of the activated carbon tank, there is an air inlet valve, and the incoming air is filtered by the activated carbon. The cooperation of these two valves can make breathing smooth.

It's very simple, just remove all the unnecessary ones.

"Xiao Li!"

The writer glanced at Xiao Li, and Xiao Li immediately put on the same gas mask himself.

How do you describe the taste of animal intestines? Huh? There is no use incense.

The writer carefully inspected Xiao Li's entire mask and confirmed that it fit seamlessly before nodding with satisfaction.

"Xiao Li, repeat what I said."

"The master said you can't squat down."

"Remember, don't squat down, don't fall down."

"Um."

He blinked his big eyes, obviously not knowing how powerful this thing was.

But you will soon know that the writer took a thoughtful look at the rabbit in the cage.

The writer took out a piece of yellow iron from a small bamboo basket.

Xiao Li accidentally discovered this thing when he was selling ice cream. It was yellow and looked like gold, but lacked a bit of metallic luster.

A stranger was selling it. The price was more expensive than copper ore. It was such a big piece, weighing about 100 kilograms. The texture was very pure.

The stranger asked for 10 friends, but no one paid any attention to him.

The price the next day was 6 cents, and knowledgeable people knew it was fake copper and didn’t buy it.

Xiao Li regarded this as a strange story and told it to the writer in the collection room.

The writer immediately understood that this was ferrous disulfide or a natural iron ore.

Solid sulfides are very stable, non-corrosive and non-toxic (provided you do not eat them directly), making them a reliable source of sulfur.

The writer's mind became more alive.

I spent two pennies on a piece of fool's gold, and then started deducing chemical formulas on the sand in the backyard.

Fortunately, the biochemistry class in 2018 was all about high-end crimes, so it was forced out of him.

fes22hcl=fecl2h2s↑s↓

The last step is so simple and crude.

The writer sealed the jar and poured a piece of sheep intestine into an air bag.

The cover of the air bag is tied tightly with metal to prevent side leakage.

This was just a test, so the writer knocked a piece of yellow iron as big as his fist, crushed it into powder and sprinkled it into the earthen jar.

Then the writer immediately sealed the jar to avoid leakage.

This step of the reaction does not require heating, and there is no fear of the jar cracking.

After a while, I heard bubbles popping up inside.

The composition of this yellow iron is still very pure, and it is probably derived from volcanic rocks.

Xiao Li watched curiously as the air bag expanded little by little. The writer estimated that it was 1/2 inflated and immediately tightened the joint.

He waved to Xiao Li, it was a bit inconvenient to speak with this mask.

Xiao Li immediately handed a deflated air bag to the writer, who tightened the valve and covered the air bag.

The fist-sized piece of pyrite was filled with two sheepskin bags.

After the gas inside stopped bubbling, the writer carefully removed the sheepskin bag, tightened the bamboo tube valve, and carried the entire earthen jar until it was under the wall of the yard before stopping and stabilizing it.

The writer wiped the sweat from his forehead, but fortunately nothing happened.

Then a prepared sprayer, made of bamboo, can only simply guide the air flow, without the effect of pressurized spray. It only has a switch and cannot adjust the size.

The spray pole is connected to the sheepskin bag. The bamboo pole is only as thick as a thumb, more than 1.5 meters.

The writer pointed the bamboo pole at the rabbit in the bamboo cage, pushed the handle, and the gas in the air bag flowed into the bamboo pole and slowly poured into the bamboo cage.

No response?

Hydrogen sulfide is a colorless gas that is flammable.

Suddenly the rabbit rioted, convulsed violently, and its limbs twitched. It stopped moving even before it screamed.

It seems that the hydrogen sulfide content should exceed the safety threshold.

The writer took a deep breath and quickly closed the valve.

When he looked back at Xiao Li, Xiao Li was so frightened that his face turned pale.

Even though the writer was mentally prepared, he was also frightened by the deathly efficiency.

So scary!

The writer saw that the purifying fire was not extinguished, so he kicked a small branch over with his foot.

The surroundings of the bamboo cage immediately burned with floating flames, crackling and flashing past.

The bamboo cage didn't burn at all, but the rabbit fur was burnt.

Burning violently, it's hydrogen sulfide.

It’s done, the writer’s hands were slightly excited.

Tap tap tap~

There was a sound of footsteps in the corridor.

But he was a warrior. He stood on the corridor and said angrily, "The gentleman is back. Xiao Li, please tidy up. The writer, the gentleman, wants to see you."

The warriors in the ancestral temple all received benefits from the writer, and a copper shell was not given in vain.

According to the agreement, they don't care about anything except the writer's escape.

Otherwise, it would be impossible to destroy a bamboo forest and break a dozen earthen pots in one day, and no one would care about him.

The samurai looked at the two people who looked like fools, turned around and left.

He muttered, "Blue-blooded man, it looks like his brain is not normal!"

Dress up in strange clothes to attract attention.

It's no wonder that the old lady in the past always made some lines in the yard and talked about what was within the light cone.

The writer is considered normal, but his clothes don't look good.

"Master, go..." Xiao Li just wanted to take off his mask.

The writer also pressed her hard on the face and said seriously, "I'll do it, or you will die!"

He picked up a branch with his feet and carefully moved it around, burning it again and again.

Those places with high concentrations burst into flames twice.

However, this is not safe, and even if the concentration is as low as a certain level, it will not burn.

The writer gently placed the two airbags under the steps and tied them to the pillars with a hemp rope.

The burned firewood was watered with well water. The fragments of earthen jars and branches were swept to the other side with a bamboo broom, then picked up and placed in a basket and handed to Xiao Li.

"Remember, don't bend down at the edge of the well."

Although the circulating air will dilute the hydrogen sulfide to a very low level, to be on the safe side, don’t be so bold in picking up soap.

After the explanation was secure, the writer remembered Ziwei's invitation.

Ziwei went to Qiucheng these two days and didn't know what to do.

The merchants who heard from Daoxing said that something big happened in the direction of Chaoge, and the entire political aftermath spread to Xibi, so Ziwei also had to make some plans.

Ziwei is going to cause trouble.
