Concentrated sulfuric acid is finally lit, this is not easy, not 98.5% of the limit concentration of concentrated sulfuric acid, did not disappoint Zhao Xin, this is also no way to do it, 98,5% sulfuric acid, need a very high purity of dilute sulfuric acid, alum oil has not undergone laboratory-level chemical sorting and refining, the purity can not be reached at all, at the current level, there are about 7% of impurities, it is already good, from alum oil to concentrated sulfuric acid, concentrated almost 10 times, that is, the original alum oil impurities are not so much. Pen ~ fun ~ pavilion www.biquge.info

Fortunately, such purity, for the present, is enough, not precise laboratory experiments, or to make something high-precision, this is just as a weapon, almost 70% of concentrated sulfuric acid has a huge lethality, 92%, as long as it shows its water absorption and oxidation is enough.

90% concentration of concentrated sulfuric acid is a strong acid, more than 70% of sulfuric acid, called concentrated sulfuric acid, impurities will make it activity weakened, can already become a good weapon, the most important thing is that when lit, it was found that its grade is level 1, not the expected level 2, that is to say, now the card system can embody him, so that Zhao Xin is a little lucky, he has always thought that concentrated sulfuric acid should be a higher level than dilute sulfuric acid, because this step, may be the difference between ancient and modern, Don't underestimate this process of steaming and transpiration, this is a breakthrough obtained after countless experiments.

After thinking about it again and again, Zhao Xin somewhat understood, concentrated sulfuric acid should be higher than this era, but if you look carefully, whether it is dilute sulfuric acid or concentrated sulfuric acid, it can be successfully made through simple processing, the former is green alum oil, cooked green alum condensation, the latter is simply steamed on the basis of green alum oil, maybe the ancient alchemists, inadvertently have made concentrated sulfuric acid, but this thing, the danger is greater, accidentally kill people, maybe the person who made him will die in its hands, Or because it is not easy to use and did not continue, not the same as alum oil, corrosive, but not strong, easy to use, has a substantial effect, his rust, some rusty or stained bronze soaked into it, the danger is not great, not a large amount of contamination on the body, there will be no danger,

5 liters of alum oil, the final concentrated sulfuric acid is about 500 ml, the previous concentration of dilute sulfuric acid, may be less than 10%, this thin is also a little powerful, after evaporating ninety percent of the water, the final amount of relatively small amount of concentrated sulfuric acid, how to load it? Among the cards, looking for a long time, Zhao Xin found a thin mouth of black pottery, did not make ceramics, the reason is very simple, porcelain is too expensive, he came to manifest, will add 30% of the cost, often is hundreds of Wen, the price of black pottery is within 20 Wen, the card system is not more than 30 Wen, continuous experiments, consumption is not small, must save a little, this is a consumable, if there is really a big war in the future, maybe there are a lot of them.

The current price of alum oil is 20 liters, and the price of concentrated sulfuric acid is 300 liters, almost 15 times the price, which is also within the acceptable range, and the pottery bottle is about 4 liters. Zhao Xingu showed about 3.5 liters, looking at the bottle full, to be sealed, he thought for a while, embodied a lead block, which is also in the city I don't know where to light up, lead is metal, but softer than iron, you can use tools to make a suitable Muyang, the preservation of concentrated sulfuric acid has no other attention, as long as it is sealed, now the best sealing material can be found is cork, cork is easy to react with concentrated sulfuric acid, but lead is better, the lead chamber is the basis for the production of concentrated sulfuric acid, concentrated sulfuric acid can react with metal, but will not react with lead, of course, iron can also, iron in contact with concentrated sulfuric acid, will soon be passivatedIt's just that the hardness of iron is large, and it is not easy to seal with iron and black pottery bottles, it is easy to damage, and iron is not suitable for processing.

After sealing it with lead, Zhao Xin breathed a sigh of relief. This is a dangerous thing, as long as it splashes out, even a little bit, it can cause harm to people, pour it on wood or paper, and because of high temperature, fire, long-term exposure to the air is not good, it can continue to adsorb water vapor in the air, and from concentrated sulfuric acid to dilute sulfuric acid, with a lead seal is the only choice, and then after completing the package, scan it, sure enough, it has changed again, a bottle of sulfuric acid, weapons, on the card has changed again, and it is lit up again, and the level has actually risen to level 3.

Interesting, Zhao Xin looked at the bottle, once again proved the previous inference, sure enough, in ancient times concentrated sulfuric acid was not recorded, not concentrated sulfuric acid was not produced, I am afraid that the creator did not know the characteristics of concentrated sulfuric acid, can not be contained, can not be used, which limits the spread of concentrated sulfuric acid, until the 1819th century, people to a certain extent of chemical research, will understand the characteristics of concentrated sulfuric acid, and the use of concentrated sulfuric acid, now, Zhao Xin has used scientific methods to create such a thing, containing sulfuric acid black pottery bottle, Coupled with the lead seal that seals the concentrated sulfuric acid, combined together, the sulfuric acid has changed from an extremely dangerous and unusable thing to a weapon-like thing that can be used safely, and the level of the card has naturally increased.

Just as oil must be a card, pyrolysis gasoline may be called level 2, this is just according to different melting points, separation methods, the overall difficulty is not great, the fact is on the basis of cooking and condensation, plus a temperature control, even in the simple equipment, can also be produced, but the gasoline barrel cotton, as well as sugar and glass bottles combined with incendiary bottles, it is not a simple thing, at least level 3, or even level 4, even in the 21st century, are terrible weapons.

It seems simple, and even the level jumps too fast, but Zhao Xin understands that this is the power of knowledge, a simple thing, is level 1, but when combined, it becomes level 3, which is also the original intention of this set of cards, strengthen hands-on ability, through mastering knowledge, so that the finished product is more powerful, perhaps in later generations, just like the 19th century, when it was created, it was used as a dye, who knew that he was a kind of medicine, and it was originally used directly in the first place. It is also after years of research that the drug effect is not a metabolite in the human body, but only a part of the metabolite in the human body, so sulfonamide was born.

The same is the power of knowledge, only knowledge is the root of everything that changes the cards, Zhao Xin finally rose to an enlightenment, the cards are the same, its role, in the hands of different users, will burst out of a completely different brilliance, in the hands of the Song Dynasty people, it is certainly impossible to have Zhao Xin so strong, the reason is very simple, the Song Dynasty people have no way to use the characteristics of the card, after understanding the price of the manifestation, they can only take risks, smuggling salt and weapons, or holding something, Selling food in remote places, or selling food when food is scarce, no matter what it is, it is ill-gotten gains. It's also easy to attract attention, whether it's salt and weapons, or food during disasters, this thing is more eye-catching, unless there is a strong background as a backing, but there is a strong background, there are too many ways to make money, why bother with it, on the contrary, Zhao Xin can change through the combination of cards and cards, and then get huge benefits.

For example, a 4-stone bow, in the army, can not be regarded as a treasure, but can be opened with the power of 1 stone 4 stone bow, it is terrible enough, its price, not only the price of 4 stone bow, is many times the price of 4 stone bow, and the production of four stone bow labor-saving devices, pulley sets and eccentric wheels, its difficulty may not be higher than the four stone bow itself, but it can make its price, into ten times, or even 100 times up, this is the advantage of scientific and technological power.

Zhao Xin once heard a story, a million-dollar machine broke down, an engineer was repairing the machine, he didn't do much, he did a line in a place, asked to cut off this line, as a result, it was because of this line, the machine was good, the engineer asked for 10,000 yuan, the communists couldn't accept it, crossed out a part, to be exact, just a little bit of machining, I'm afraid it was not even 1 dollar, why so much money, the engineer was vibrating, yes, processing a part, Any worker, or an ordinary person, with the help of tools, can do it, but it is not easy to find the location of the broken part and draw a certain line, which will definitely cost $10,000.

This story is true, even in the early days of reform and opening up, because of this suffered a lot of losses, but it was also helpless, foreign products can not be repaired, must be repaired by foreign engineers, the price is expensive, and some losses, converted to the current concentrated sulfuric acid, how is it not so, from the accidental alum oil, to concentrated sulfuric acid, just a steaming process, there were genius alchemists in ancient times, completed this move, which is also the fundamental reason why concentrated sulfuric acid is classified as level 1.

Simple concentrated sulfuric acid itself, if you don't recognize his role, he is also a slightly rarer thing than dilute sulfuric acid, and many of his effects have not been exerted at all, and this understanding, which seems simple, is only possible after hundreds of years, or even millennia, such as putting concentrated sulfuric acid into a bottle to form a container-like, weapon-like thing.

Of course, Zhao Xin's cognition is also limited, this is based on the 32nd century technology, from the 21st century to the 32nd century, the same more than 1000 years, this is also the 1000 years of rapid development of science and technology, just like the Song Dynasty If you can travel to the 21st century, he will think that this is an incredible paradise, full of incomprehensible mysterious substances, if Zhao Xin is in the 32nd century, I am afraid it is almost the same, if you want to fully exert the power of the card system, I am afraid you really need a creator, in his hands, This card system, based on the idea of unification and quark, may be an extremely powerful weapon.
