The resident card will also appear in an unopened state, which makes Zhao Xin strange, these cards he lit up are all open, and they can be used directly when they are taken out, is it a more advanced card, there is a state of opening and closing, how to open, money, lottery, or level, maybe this is a second-level card, the most obvious first-level icon proves its identity, he is a first-level card, but it is just a purple rare card. Pen ~ fun ~ pavilion www.biquge.info

The whole card system is quite intelligent, Zhao Xin put his consciousness in the cards, and one by one the instructions were displayed, and soon he understood why, because the front cards were not enough, so they couldn't be opened.

Pre-loaded cards and system cards, which are rarer than the general card system, represent a special card system, and generally at least blue rare cards can have such a system.

To open Ancient Chemistry, you must light up 5 basic level 1 chemistry cards, which are, sulfuric acid, nitric acid, hydrochloric acid, and soda ash and caustic soda.

This is not three acids and two alkalis, this is also the foundation of the future modern chemical industry, all chemical systems, all are based on such three acids and two alkalis, Zhao Xin is currently lit, only sulfuric acid and soda ash.

In ancient times, only sulfuric acid can be made by a simple reaction, the others are more complex processes, sulfuric acid is the foundation of everything, a little chemical basis, you can make other products through sulfuric acid, the remaining two acids, are strong acids to make weak acid reaction, as for the caustic soda, take more simple, soda ash can be a simple reaction with lime milk to generate caustic soda, which is one of the important methods to make caustic soda.

The chemistry knowledge at the beginning of high school, basically, can complete the production of various acids and bases.

Carefully recalled, there are not too many problems, because all are toxic and corrosive substances, containers, only copper can be selected, just a lighting process, and nothing else, as long as the concentration reaches a certain level,

Sulfuric acid is indeed the root of everything, it is the basis of all acids and bases, and can be used as the basis for the transformation of other acids and bases.

The simplest is caustic soda, soda ash reacts with lime gypsum, and caustic soda in the solution is the simplest process. The rest is not difficult, table salt reacts with concentrated sulfuric acid, and hydrochloric acid can be made directly, both of which are simple reactions.

Zhao Xin embodied these materials, because they are all reacted at room temperature, and two clay pots and a stirring stick were prepared, which could speed up the reaction.

The reaction between soda ash and lime paste is more violent, and the reaction between concentrated sulfuric acid and table salt is the same, in the reaction, the card system has been lit twice, the purity of caustic soda is about 85%, and the purity is 92% of concentrated hydrochloric acid.

With the help of the same basic acid and alkali, the production of caustic soda and hydrochloric acid was completed, and when the card system was lit, the number of the pre-card of ancient chemistry changed from 2/5 to 4/5, and only the last one remained.

The five basic three acids and two alkalis, the lighting of 4 has been completed, and there is only the last step away from opening ancient chemistry, and this step is still the most difficult step, nitric acid.

In the three acids and two alkalis, but nitric acid is more difficult, in fact, nitric acid is also three acids and two alkalis are more important, all explosive materials have a direct relationship with nitrate, nitric acid is the most basic, but also the most closely related to the war of an acid, relative to the hydrochloric acid and sulfuric acid that can be stable at room temperature, nitric acid is not only very unstable, but also more difficult to make.

China has invented gunpowder, especially the use of plant ash and nitrate to make saltpeter, most of which is a mixture of potassium nitrate and sodium nitrate, sodium nitrate can react with concentrated sulfuric acid at room temperature, potassium nitrate is not, it is an ionic state, it must be heated, and the heat is not too high, otherwise nitric acid is easy to decompose.

Zhao Xin made two preparations, on the one hand, did a simple heating, on the other hand, also to prevent the decomposition of nitric acid, made a condensing device, after the decomposition of nitric acid, the water vapor produced, containing nitrogen dioxide and water vapor, after condensation, is dilute nitric acid, and then can be distilled under atmospheric pressure to obtain 69% nitric acid, at high concentrations can be added concentrated sulfuric acid distillation and dehydration, up to 90%, or add magnesium nitrate for purification.

Magnesium nitrate can't be obtained for the time being, Zhao Xin can only try the previous method, if it is not lit for the time being, more than 60% is enough.

A device for heating reaction, a device for condensation, and many unexpected states to consider, for which Zhao Xin specially prepared every day.

Zhao Xin is making something again, this is the news from Sun Ji, Miao Yuan came in a hurry, respectfully waiting for Zhao Xin to introduce, what is this thing.

But after looking at it for a long time, he couldn't tell the difference, the powder, ore, and liquid, especially the pungent smell, he even wanted to reach out and touch it.

"Be careful!" Seeing that Miao Yuan wanted to reach out and touch the mixed acid that was helping to purify concentrated nitric acid, Zhao Xin was startled, this concentration is not the highest, but it is also very dangerous, Miao Yuan's reaching into it is fatal.

The sudden voice made Miao Yuan shrink his hand violently, startled by Zhao Xin's movements, and asked puzzledly: "Fourth Young Master, what is this?" ”

"This is a very dangerous thing!" After Zhao Xin finished speaking, he used a ceramic spoon, got a little bit, and threw it on a piece of wood, with a strong reaction and dehydration, and directly reduced the wood to carbon.

Miao Yuan didn't dare to move, and Sun Ji, who had been watching calmly next to him, was also quite surprised, but at this moment, there was no way to make Zhao Xin stop, these might be the Dan Dao of the Immortals, and they didn't dare to stop it at will.

Soon, these experiments were completed one by one, and Zhao Xin also successfully lit up several basic chemical raw materials, especially the last nitric acid, even if various methods were used, the first reaction failed, and the second, colorless liquid, under the transpiration of heat, generated brown-red gas, and then condensed and dissolved into water, generating very meager dilute nitric acid.

After a series of transpiration processing, dilute nitric acid finally became about 60 concentrated nitric acid, and then it was a little difficult, Zhao Xin could not make the purest nitric acid, so he could only give up.

It took a little effort, and finally lit up the three acids and two alkalis, all the preconditions for ancient chemistry were reached, and in the card system, the icon of ancient chemistry was opened, and if you look carefully at the introduction, the above introduction made Zhao Xin overjoyed, purple is really powerful, and it contains two abilities, both of which are closely related to chemistry.

First of all, after the resident ancient chemistry, the price of all chemical raw materials related to chemistry has been reduced by 35%, 35% This is almost more than one-third of the time, that is to say, soda ash, salt, including some other chemical raw materials, their actual price, all reduced by 35%, this is not a small amount, Zhao Xin is stronger than this era, I am afraid that the most is chemistry, many things are directly related to chemistry,

The overall price is reduced by 35%, which means that he can make more money, especially the use of three acids and two alkalis, which has a huge range of use, and will be used more and more in the future, and their costs will occupy a large part of Zhao Xin's current appearance.

One reduction is that the time it takes for chemicals to manifest is reduced by 50%, which is also a benefit, and in the same amount of time, he can manifest more things.

Take soda ash as an example, soda ash can be said to be extremely widely used, if the entire Northern Song Dynasty, 100 million people, are included in the scope of soda ash use, the total amount of soda ash will be very huge, but Zhao Xin is currently able to produce 14,400 catties per day, an increase of 50%, which means that in the same time, Zhao Xin can produce an additional 7,200 catties, which is up to 1 pound per catty of soda ash, the increase is very amazing.

Reduce the price, increase the speed, this is all about the improvement of the embodiment itself, useful, but more of a problem with money, next, a special ability of the purple skill, is closely related to chemistry, with the help of this card system, you can remove 3.5% of the impurities, this is a special ability.

3.4% increase in purity of all chemical raw materials

Don't underestimate this, for ordinary chemistry, to achieve about 97% purity, it is not an easy thing, but under the effort, it may not be impossible to do, as for later, from 99% to 99.99, or even to the purity of four 9s, it seems that the purity has only increased to less than one percent, but it costs energy and money, that is an astronomical amount.

Different impurities, different purity, the external manifestation of the material, there will also be a huge difference, purity, always in the chemical system, the most important, but also the most worthy of effort to improve the thing, higher purity of raw materials, in the process of manufacturing and production, less consumption, higher accuracy, higher output.

Not to mention the last 3.5%, the last 1% degree is the most difficult, a lot of chemical raw materials, even if the purity is increased by 1%, or even 0.1% is a big progress, some chemical properties will bring a lot of changes, all of a sudden increase of 3%, which represents the changes in the sky and the earth, it seems that all of a sudden, this chemical raw material, will be from the roughest, to the precision closer.

For example, concentrated sulfuric acid, he can easily reach 98.5% purity, but it needs 100%, which is not good, at least not in the current state. In later generations, when chemistry was extremely developed, it was difficult to make concentrated sulfuric acid with a purity of 100%, but with the function of this ancient chemistry, it was directly possible.

These are just three benefits, and they are also the most intuitive methods, which are very powerful, and also allow the many systems related to chemistry to get the most promotion.

However, after Zhao Xin's careful study, he found that the biggest benefit is actually still to come, the reaction method of 300 kinds of chemical raw materials, this is probably the biggest gain.

These 300 kinds have appeared in ancient times, and they can be made by simple means, which is an unexpected surprise.
