The solar system is broken

Two days ago, in the backyard and in front of the well.

The writer looked at the bottles and jars filled with salt brine and was very satisfied.

The so-called salt brine is the magic tool for ordering tofu, brine alkali.

It comes from a wide range of sources. It can be obtained by evaporating and cooling the mother liquor remaining in the salt pond after making salt from seawater or salt lake water. The main component is precipitated magnesium chloride crystals.

But what the writer made was a solution, which was light yellow, astringent, and bitter.

However, this solution does not quite meet the standards. The only active ingredient the writer needs is magnesium chloride.

Simple evaporation and purification will darken the color of the liquid solution.

Brine contains sodium chloride, potassium chloride, magnesium chloride, calcium chloride, magnesium sulfate, magnesium bromide, etc. This wait is very subtle.

Generally speaking, the proportion of this initial solution is: magnesium chloride accounts for 15% to 19%, magnesium sulfate accounts for 6% to 9%, potassium chloride accounts for 2% to 4%, and sodium chloride accounts for 2%

~6%, magnesium bromide content accounts for 0.2%~0.4%

Fortunately, these ingredients do not affect the writer's operation. Although impurities will be produced during the preparation of hydrochloric acid, mixed acid will be formed and will have no impact on subsequent processes.

The principle is still unpretentious, simple and boring.

2mgcl2h2o===mgo·mgcl2↓2hcl (reaction conditions: heating to 110-120℃)

But this equation is not very good, it is reversible.

But the problem is not big, at most it is just that the quantity produced is less.

The writer actually knows the process of making acid from brine very well. He even has a complete process for making it, which is a hundred million points simple.

(1) The brine is deaminated and salted, and then sent to brine for refining to obtain refined brine.

(2) The refined brine is processed in a resin tower to obtain ultrapure brine.

(3) The ultrapure brine is electrolyzed to obtain hydrogen and chlorine gas. The remaining light brine after electrolysis is concentrated and salted and sent to step (1) to neutralize the salt; (4) the hydrogen is treated with hydrogen

, the chlorine gas is treated with chlorine gas, and then hydrogen chloride is synthesized to obtain the finished product hydrochloric acid. The residual hydrogen chloride gas after the hydrogen chloride synthesis is absorbed to obtain a hydrochloric acid solution, which is sent to the resin tower treatment process in step (2).

Not to mention the production method of this process, these complete sets of equipment alone are beyond what the author can do.

As a man of perseverance, he designed a low-profile version of the package.

Ask Xiao Li to buy a few earthen jars, make a hole in the abdomen, insert a bamboo tube, and seal it with wet soil.

I originally wanted to find a teapot instead, but I didn't have the conditions.

Fill the earthen pot with brine and then bake it continuously over firewood.

110-120 degrees Celsius, the writer has no way to estimate.

In fact, there is no way to solve it. Just put a large clay pot outside the brine, fill it with water and pressurize it to increase the boiling point of the water, and judge the temperature through precipitation.

However, the writer didn't care about this, he just sealed the brine pipe and started adding firewood.

He can also pressurize it, but the effect will be much worse and it will easily crack.

The bamboo tube is first plugged with a cork, and the earthen jar slowly turns black.

Xiao Li looked at the earthen pot and timidly asked the writer, "Master, what are you doing?"

Why call me master?

The writer felt that a gentleman was not pleasant to hear, so he took it from the image of the master in Japanese comics. This image is extremely elegant, Su Qing らしい (Japanese, pronounced subarashi, wonderful).

"Hydrochloric acid!" The writer dragged his chin and watched nervously as the crock turned black little by little (because the charcoal was not completely burned).

"Can I sell it for money?"

...

The writer has made a lot of money recently and bought a lot of things.

There are more than a dozen skins piled up in the side room, and I don’t know what the writer wants to do.

Xiao Li asked him, but the writer just gave a perfunctory answer and didn't answer.

"Xiao Li, do you want to..." Turning around, there were no warriors in the corridor. In fact, they had become much more relaxed and didn't even check the writer's things.

"Do you want to be free~"

How could a slave who has been a slave for more than thirty years not want freedom?

I just follow the writer, and I have more money on hand these days, which makes me feel better.

"Yeah!" nodded.

The writer touched Xiao Li's head and said gently, "Believe me."

Although I have been a liberal arts man for more than ten years, I still haven’t forgotten my roots in simple physical education.

"Well, Master, it's broken~"

"??"

It broke! The yellow liquid flowed all over the floor.

Damn it, I forgot about the real business of flirting with girls.

The white crystals quickly dissipate in the rapidly cooling solution.

feasible.

The writer's eyes lit up.

The precipitate is naturally the precipitated crystals of magnesium chloride, but as the hydrolysis reverses, it forms magnesium chloride hexahydrate and dissipates.

It worked.

However, the quality of this earthen jar is too poor. It cannot withstand the low temperature of more than 200 degrees and is too fragile.

Thinking of this, he cast his eyes towards the bronze gui in the room.

Xiao Li was so frightened that his face turned pale and he kept saying, "Master, this is not allowed."

The writer also thought that if it was really used, Ziwei would have to chop him several times.

The value of a bronze product was ridiculously high in this era.

As mentioned earlier, a pile of copper shells is equivalent to about 120 kilograms of corn, one copper shell is about 12 grams, and ten copper shells are equivalent to 120 grams.

A copper gui weighs about 20 kilograms, which is nearly 150 kilograms of currency. This does not include its craftsmanship value, it is purely material value.

The writer only used one tripod and one Gui, which can be regarded as Ziwei’s fault.

Ziwei himself only had seven tripods and seven guis, plus some bronze earthenware and fou. Of course, these were only the utensils Ziwei had in the ancestral temple.

The writer is in a bit of a dilemma. The crock pot craftsmanship is not proficient, and there are some consumables for making hydrochloric acid.

But there was no other way. It was successful after all, and the worst I could do was buy dozens more crocks.

Anyway, one copper shell can buy a dozen earthen jars, which can be made easily.

The warrior walked under the oak tree and looked up at the oak tree above his head.

The oak trees have begun to wither, and only the golden branches flourish.

This mistletoe plant is actually a parasitic plant.

Shrub, 0.3-0.8 meters high; stems and branches are cylindrical, dichotomous or trichotomous, sparsely branched, slightly larger nodes, internode length of small branches 5-10 cm, 3-5 mm thick, after drying

With irregular wrinkles.

The most important thing is that it can be used as medicine to nourish the body and kidneys, and prevent pregnancy.

This small shrub will grow an orange-red ball every late autumn.

The main method of propagation of this tree is by the Eastern bluebird, which then excretes it into the tree, and it takes 3 to 5 years for it to germinate.

But a very interesting phenomenon is that when mistletoe falls on mistletoe, mistletoe will grow.

The warrior carefully looked at the golden branch above his head. From time to time, he had the idea of ​​becoming a rebel.

But someone had done it before and it became fertilizer for oak trees.

"Ah~" the writer yelled from the backyard.

"He's broken again! The unruly people who stepped on the horse dare to break it!"

"Master, the water is flowing out, what should I do?"

"Don't move, that water is very precious, let me pick it up~"

"But..."

The corners of the warrior's mouth twitched, and the slaves were more prosperous than him.
