Pomegranate takes out a clay pot and fills it with some water to melt off the salt. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The thin body struggled to pull out a set of batteries.

After connecting the circuit, the little pomegranate raised his head and asked, "Brother Yi, the brine will turn green with copper electrodes, is there a graphite electrode?" ”

Sun Yi's mind buzzed.

The chemistry textbooks in junior high school never talked about this, and Sun Yi never thought about it.

Indeed, as Pomegranate said, if a copper electrode is used, the copper of the anode will be corroded away to form a green copper ion solution, which is the same principle as electrolytic copper.

This shows that Pomegranate has carefully done experiments on electrolytic saline, but he has never practiced it.

"Pomegranate", Sun Yi slowed his tone, "Tell me about the steps of your electrolysis of saline." ”

Little Pomegranate recounted that Sun Yi found that in addition to replacing the electrode material, the other steps were not too special.

Finally, the pomegranate said: "The whole electrolysis will take several days, and the soil salt is better than the refined salt." ”

At this time, Sun Yi was already convinced that Little Pomegranate was not lying.

Sun Yi opened the mobile phone database and carefully searched for information about electrolyzed saline.

All the information is brief and unambiguous to indicate that the final product is caustic soda.

Sun Baibai was puzzled, the product of the electrolyzed brine of the small pomegranate obviously had nothing to do with caustic soda.

Just before he was about to turn off his phone, he habitually switched to English.

It was purely a subconscious action, because Sun Yi was very unfamiliar with the English vocabulary of chemistry.

Sun Yi was stunned.

The first sentence of the English source says that the products of electrolyzed saline are very complex.

Sun Yi was relieved, and while consulting professional vocabulary, he slowly gnawed on this professional information.

According to the information, the industrial electrolysis of salt water to produce caustic soda actually requires a special electrolyzer and an ion exchange membrane.

Sun Yi secretly scolded, it turned out to be the same old problem again: theory is theory, practice is practice, and theoretical things will not work in practice.

Just like physics in middle school, all the exercises ignore air resistance and friction, but in reality, engineers are mainly working with these two forces.

In the junior high school chemistry textbook about the electrolysis of salt water, the reaction equation in the ideal state is directly given without saying a word, and there is no hint of "ignoring air resistance and ignoring friction" in physics textbooks.

English data further shows that in practice, the chlorine produced by the cathode of electrolyzed salt water will be dissolved in water, and further participate in the subsequent reaction to form hypochlorite, which is bleach.

When the energized temperature rises, the bleach reacts again to form chlorate.

I see!

No wonder all Chinese sources don't mention it!

Thinking of the words of the little pomegranate, Sun Yi suddenly woke up to the fact that because the solubility of potassium salt of chlorate is lower than that of sodium salt, it is particularly easy to precipitate in soil salt.

Sun Yi suddenly danced excitedly and shouted that the guards should adjust the best lead-acid battery! Tune the best graphite electrode to come!

Everyone looked at Sun Yi strangely.

Sun Yi bent down and said to Pomegranate, "You didn't lie! It was me who was wrong! What rewards do you want? ”

The little pomegranate refers to the dumplings.

Sun Yi shook his head, "It's only a meal of dumplings, and the reward is too light!" ”

Little Pomegranate stretched out two fingers, hesitated and turned into three, "Is it okay to eat dumplings?" ”

"Good!"

Sun Yi happily agreed to the pomegranate.

Then Sun Yi asked again: "Pomegranate, what about the Hero Medal that made you electroplated?" ”

The little pomegranate trotted to fetch a few golden medals.

These medals are in the shape of a pentagram, embedded with a taiji diagram, the internal material is tin, and the outer surface is electroplated with a layer of copper, and the electroplating work is the responsibility of the small pomegranate.

Sun Yi took out a medal and hung it around the neck of the little pomegranate, "Pomegranate, you will be a hero in the future." ”

Yang Nai'e hurriedly picked the pomegranate for her, "Master, the pomegranate is still young, this kind of joke can't be made!" ”

Sun Yi was stunned and said, "It's okay." You take care of the medal for her, and the pomegranate will grow up and give it to her. ”

At that moment, Sun Yi hastily put a few mouthfuls of dumplings and plunged into the crockpot pile of batteries and salt water.

Sun Yi devised several methods.

Some directly electrolyze soil salts, some directly electrolyze boiled potassium salts, and some electrolyze refined salts to obtain bleach before reacting.

Two hours later, after some filtration, evaporation, and crystallization, Sun Yi got a few small piles of white flake crystals.

These are either potassium or sodium salts of chloric acid. Both are strong oxidants, and the only advantage of potash is that it is not easy to absorb water and become wet.

Sun Yi solemnly invited the chief soldier Yang Ritian.

In front of Yang Ritian, Sun Yi mixed the willow charcoal with black powder with a pile of white crystals and loaded it into the electric three-eyed gun.

"Master, you forgot to put sulfur in it." , Yang Zongbing reminded him.

Sun Yi shook his head, "I'm afraid it's too dangerous." ”

Sun fixed the three-eyed gun to the tree, pointed to the empty space, and took out two long wires from a distance.

Sun Yi pressed the electric door,

"Pounds!"

The three-eyed gun was blown up more than a person tall.

Yang Ritian ran over and picked up the three-eyed gun, but the gun tube was already cracked.

Yang Ritian said strangely: "How can you be so strong without sulfur?" ”

Sun Yi smiled slightly: "The white powder used now is not the fire powder of the past. The medicine prepared with fire nitrate is called gunpowder, and the medicine prepared with this white powder is called explosives! ”

Sun Yi took a small clay pot, filled it with white crystals and sugar, buried it in the soil, and detonated it with a battery from the same distance.

"Boom!"

The crockpot crushes and lifts up a layer of soil.

Yang Ritian sighed: "If there is someone next to this, it must not be blown into bone slag!" ”

Sun Yi added the oil of stir-frying vegetables to the white crystals, wrapped it in a cloth, and also led out the battery wires far away.

"Boom."

Both of them felt a wave of air, and the blades of grass fell.

Sun Yi finally understood a question that had plagued him for many years: what was going on with the explosives package that Dong Cunrui blew up the bunker.

"Master, what the hell is going on with this explosive?" , Yang Ritian couldn't help but ask.

Sun Yi replied rationally: "You also saw it just now, the three-eyed gun is no problem with gunpowder, and it will explode if it is replaced with explosives." To put it simply, this explosive is gunpowder that is 100 times more powerful than ordinary gunpowder. You imagine that we can make bombs out of explosives, drop them by hand, shoot them with arrows, or even fire them with grenadiers. ”

"Oh my God! With this thing, I'm afraid that no one will be our opponent in the future battle! ”

"In theory, we have to have enough explosives."

"Master, is this explosive good? Is it expensive? ”

"Made of salt, found by the pomegranate."

"Is it really salt?!" , Yang Ritian's mouth opened widely, "Isn't that how much salt can make as much explosives?" ”

Sun Yi corrected, "In the process of making explosives, electricity is consumed, and it should be said that as much electricity can be used to make as much explosives." ”

Yang Ritian immediately suggested: "Master, set up an explosives workshop immediately!" ”

Sun Yi replied: "Don't rush first. ”

"The explosives are too powerful now, and we have to find a way to reduce the power of the explosives first. Otherwise, it is easy to blow up by mistake and hurt your own people. Moreover, I am still figuring out how to produce it, and now only the pomegranate can help. ”

Sun Yi continued: "I rewarded the little pomegranate with a hero's fame and said hello to you. ”

Yang Ritian said: "It should be, it should be." ”

"Pomegranate is too young, I mean don't publicize the reward of this hero first, and then make it public when she is older, you can help me remember it."

Yang Ritian happily agreed: "Success!" ”

Sun Yiyi smiled: "So, our pomegranate's reward now is three dumplings." ”
