Cu aqua regia. The composition of royal vodka. HCl hydrochloric acid

11.07.2020

Academician Bolotov had his own idea about the treatment of many diseases, especially those that are commonly called incurable. For many years he was engaged in such sciences as chemistry, biology and physics. Official medicine today shows more and more “misfires”, while traditional medicine, on the contrary, is gaining popularity. Such famous scientists as Bolotov, Neumyvakin and others, open up medicine to us from the other side.

Despite the fact that among the supporters of traditional methods of treatment, many facts remain unrecognized, people often use unconventional methods. In the article we will talk about such a tool as Bolotov's balm. It sometimes causes even resentment among doctors. But people have the right to choose how to heal their body.

Aqua regia

Mention of this product was first found in the Middle Ages, in the fourteenth century. And before that, many alchemists tried to develop her recipe by mixing ammonia, vitriol and other substances. Hydrochloric acid was not yet invented at that time. But the goal was a solvent formula that could act on noble metals. He became the royal imperial vodka. She was able to dissolve even the elements of gold, which at that time were considered indestructible.

Composition

So, aqua regia is an acid that is formed from two acids in high concentration. Three parts of nitric acid were added one part of hydrochloric acid. Sometimes sulfuric was mixed with it. The result was a transparent liquid, which gradually acquired a yellow-orange hue. At the same time, a pronounced smell of chlorine was released and A such vapor is dangerous for humans. The product was strictly forbidden to use inside.

Today it is used for sterility and metal separation. And in the Middle Ages, liquid was used in torture. Today, alcoholic beverages have been developed based on aqua regia. Among them, the famous is Tsarskaya and Tsarskoye Selo vodka. The latter belongs to the premium category.

Bolotov Balm

The scientist has developed 5 rules on which the principles of a healthy life are based. These include:

multiplication of the number of young cells in the body;
conversion to salt of slag;
excretion of salts;
the fight against harmful microorganisms;
restoration of internal organs.

To achieve the above goals will help Bolotov Balm, which he developed on the basis of imperial vodka. People doubt the usefulness of the remedy, based on its composition. How can sulfuric, hydrochloric and have a positive effect on the state of the body? However, it is all about concentration.

Today, Bolotov's balm is used not only in treatment, but also as a prophylactic. In some cases, it can cure serious diseases, as well as significantly strengthen the immune system. For example, the product neutralizes harmful substances that accumulate during sleep. Therefore, his morning reception will help a person to find vitality for the whole next day.

Application

Consider the most common goals for taking this medication inside:

The creation of pepsins (special enzymes of gastric juice) is stimulated.
Low secretion of gastric juice and zero acidity come back to normal.
Blood liquefies.
High sugar content returns to normal, and blood vessels are cleaned of fatty acids.
The body is rejuvenated.
Old and diseased cells break down.
Heartburn, ulcer, hemorrhoids, gastritis, herpes and other diseases pass.
Immunity is strengthened.
The operation of the gastrointestinal tract system is normalized.
are split.
Free radicals are neutralized.
Such diseases as vascular atherosclerosis, heart attack, stroke, arrhythmia are prevented.
In addition, the poison of the protein that forms during AIDS is neutralized, and different types of cancer cells are split.

Recipe

The tool is purchased in finished form. However, they do it on their own. Let's consider how Bolotov's balm is prepared. The recipe should be followed exactly. Otherwise, he will not only not show his healing properties, but can also harm the body.

For one liter of water add:

100 milliliters of 6% grape vinegar;
from one to two small spoons of 98% sulfuric acid;
from one to two small spoons of 36% hydrochloric acid;
four tablets of nitroglycerin.

The ingredients are added in the order indicated and mixed thoroughly.

How to use

Take one to two small spoons three times a day before meals or dissolve in tea, compote or coffee after eating. At the same time, a minimal dose is enough to treat a serious disease. And the maximum can be two large spoons, which are taken four times a day. It is useful to drink Tsar’s Balotov Balm immediately after sleep.

Reception begins with a minimum dose. Each week add one small spoon. If an exacerbation of the disease is felt, then on such a day they do not drink the drug, and the next time they resume taking it at the dose that was the previous week. Do not be afraid of exacerbations of the disease. This just indicates that the body is being cleansed and healed. Following the exacerbations comes complete deliverance from chronic diseases. They will manifest themselves in a lighter form.

Gangrene Balm

Gangrene develops with burns, injuries and frostbite. It also occurs with vascular diseases, endarteritis and diabetes. In most cases, gangrene amputates limbs.

According to the scientist, this effect can be avoided if you take high doses of balm. In this case, the course of treatment is from two weeks to a month. Every day they drink from three to six times a day, 30-50 ml of the drug. Then the gangrene will stop. This fact was called the Bolotov phenomenon number 27. It develops with a shift in the balance of the birth of cells and their dissolution.

It turns out that a certain number of cells die. As many of them are dissolved in the body. But with gangrene, there are fewer dissolving cells than dying cells. Therefore, an imbalance occurs when Bolotov's balm - “Tsarist Vodka” is used.

It should be emphasized that the drug helps to dissolve only dead cells. It does not affect the living. That is why the gangrene process stops. This phenomenon affects all types of this disease.

Bolotov Balm: reviews

There are heated discussions about the usefulness of the tool. Some people are sure of a positive effect and have already been treated by it. Others make fun of the scientist and ask: “Why didn’t he and his relatives rejuvenate?” It is clear that serious research should be carried out and officially proved whether Bolotov's balm is useful. Reviews of doctors due to lack of information and research are mostly negative.

But, on the other hand, there is an opinion that for official medicine, the goal is not human health, but his painful condition. Otherwise, where to go to the entire pharmacological industry, which receives tremendous profits, and unscrupulous doctors living by treating patients? Proponents of this position believe that this is the reason for the constant negative position of official medicine in relation to all that, with the help of which human health can be improved almost for free. There may be many opinions, but you need to be very careful about folk remedies, like medicines.

Ask the foreigner what is the national drink in Russia, and you will get the answer - vodka. Back in the 14th century, “water of life” was first brought to Russia and presented to Prince Dmitry Donskoy. In the 15th century, it began to be produced in our country.

Tsarist Original was first released in 2003 to mark the 300th anniversary of the founding of St. Petersburg for the festive events. From this began the history of the Ladoga factory producing vodka under a sonorous brand.

Tsarskaya Zolotaya in 2006 received the status of the official drink of the G8 summit, which was held in Strelna (district of St. Petersburg).

The Czar’s Original line was originally developed for the markets of the USA, England and Germany, where flavored vodkas are very popular. Later, after conducting a marketing research among our compatriots, a decision was made to bring drinks to the Russian market.

Imperial acid vodka can be purchased at stores specializing in industrial chemistry. There are not many of them, but you can find them on the Internet. It is not difficult to praise royal home-made vodka, especially if you made it yourself. But about purchased vodka, bottled at the factory, it is difficult to make a certain opinion.

The quality and beautiful performance of Tsarskaya vodka provide its customers with positive feedback. The oxidizing properties of aqua regia disappear during storage, because chlorine evaporates from it in the air, namely it is the main one in oxidation reactions. Thus the name aqua regia (also aqua regis, A.R.) appeared.

The fact of the dissolution of precious metals in aqua regia was considered by alchemists as a solution to one of the most important tasks of alchemy: the preparation of alkagest - a universal solvent. Imperial vodka is capable of dissolving not only gold, but also platinum. How does royal vodka affect precious metals?

Imperial vodka and alchemy

In the alchemy of Andreas Libavius \u200b\u200bfor 1597, the production of aqua regia by mixing saturated hydrochloric and nitric acids was first described. Alkagest is a universal solvent. Its preparation was considered as the solution to one of the most important tasks of alchemy.

Imperial vodka was used quite often in the practice of alchemy. This has led to a significant increase in knowledge of chemical reactions and substances. In addition, similar experiments contributed to the development of technical chemistry and assay analysis.

In the works of Lavoisier, the formula of “royal” vodka was called nitromuric acid. Scientists thought that chlorine released in a gaseous state is an oxide of the element of muria or dephlogistically hydrochloric acid.

In Russia, she had many names. In the works of M.V. Lomonosov in 1742, it has the name of "royal vodka." M. Parpua in 1796 called it "royal vodka." V.V. Petrov in 1801 gave her the name nitrochloric acid, and G.I. Hess in 1831 called it nitric acid. Other names for this fluid are common.

In Russian, the word "vodka" appeared in the fourteenth century. It was a diminutive of the word "water" and had this meaning until the mid-nineteenth century. Further, this word received the meaning of “alcoholic beverage,” at first it was dialectic. It was only at the beginning of the twentieth century that vodka began to mean strong alcohol.

History of Research and Use

Fox - an alchemical image of royal vodka on an engraving from the Book of the Twelve Keys by Vasily Valentin, Musaeum hermeticum, 1678

Long before the discovery of hydrochloric acid in Latin texts attributed to the Arabian-Persian alchemist Geber (Jabir ibn Hayyan) (VIII century), a method for producing royal vodka by dry distillation of a mixture of nitrate, copper sulfate, alum and ammonia in a glass, well-oiled vessel equipped with glass lid or cap.

In the writings of Albert the Great, it is called aqua secunda (“Secondary vodka”, and “primary vodka” - aqua prima - nitric acid), with other alchemists - aqua regia. In 1270, Bonaventure pointed to his own method of obtaining the dissolution of ammonia in “strong vodka” ( aqua fortis, Nitric acid). Bonaventure also found that nitric acid dissolves silver, separating it from gold; using royal vodka, he established its ability to dissolve the “king of metals" - gold, which for some time was considered unaffected by change. Thus the name appeared aqua regia (also aqua regis, A.R.) The alchemical symbol of aqua regia was composed of the sign of water

and the capital letter R. Later, aqua regia was described by Pseudo-Geber, an unknown alchemist whose treatises began to spread in Europe in the 14th century.

The preparation of aqua regia by mixing concentrated hydrochloric and nitric acids was first described in Alchemy by Andreas Libavius \u200b\u200b(1597). The fact of the dissolution of precious metals in aqua regia was considered by alchemists as a solution to one of the most important tasks of alchemy: the preparation of alkagest - a universal solvent. The use of aqua regia in alchemical practice led to a significant increase in knowledge about substances and chemical reactions and contributed to the establishment of assay analysis and technical chemistry.

In Lavoisier’s works, aqua regia was called “nitromuric acid,” in accordance with the notion that the gas (chlorine) released is nothing but the oxide of the element of muria, dephlogic hydrochloric acid.

In Russia

In Russia, it was called royal vodka (M.V. Lomonosov, 1742), royal vodka (M. Parpua, 1796), nitrate-hydrochloric acid (V.V. Petrov, 1801), and nitric-hydrochloric acid (G I. Hess, 1831); other names are known. The word "vodka" originally appeared in the Russian language around the 13th-14th centuries as a diminutive of the word "water" and had such a basic meaning until the mid-19th century. The word “vodka” acquired the meaning of “alcoholic beverage” somewhere between the fourteenth and nineteenth centuries, initially as a dialect, and only at the end of the nineteenth and beginning of the twentieth centuries did it mean the only “strong alcoholic beverage”.

The method of preparation of royal water

To prepare your own royal vodka you will need:

concentrated HCl, HNO3;
glass test tube;
glass rod.

First of all, you must accurately measure the right amount of reagents. We remind you that you need to mix three parts of hydrochloric acid with one part of nitric acid. Do not think to measure the amount of fluid by eye. The slightest inaccuracy will lead to the fact that the reagent will be weak in efficiency. It is best to take a glass test tube with the divisions on which you will navigate.
Try to use the minimum amount of dishes. And also try to transfer less reagents from one test tube to another. Beware of spilling them.
We recommend that you first add hydrochloric acid to the tube, and then add nitric acid to it. This is to ensure that when you pour less liquid into more liquid, reduce the amount of spray. Pour the acid carefully with a thin stream. Do not bring the acid tube close to your face to prevent accidentally inhaling fumes.
When you have mixed all the reagents, gently mix the mixture with a glass rod. It is necessary to mix thoroughly so that all reagents react among themselves, and not just stratify. In no case, do not shake the tube. If you did everything right, then the liquid you mix will initially be yellow, and after half an hour it will darken to orange.

Around the dispenser you can read "Tsarskaya". By law, a federal brand on a bottle of vodka.

How and with what to drink Tsarskaya vodka?

A special drink requires a special attitude. Tsarskaya vodka is advised to drink royally: a cold drink in a crystal decanter and piles, and a snack on the tablecloth from spoilage. The snack should be different: herring with onions, tomatoes, squash, red and black caviar. The meat should be without spices, so that the taste of the drink was felt. Grilled meats will be very appropriate.

You need to enjoy the drink slowly. Sit back in the chair. Imagine yourself a master. Nobleman's fur, of course, is not necessary, but a decanter for vodka is desirable. Of course, it is better to drink cold.

It is a mixture of acids of high concentration, and therefore - the strongest poison. The effect of this mixture on the human body is terrible even to imagine - after all, aqua regia is able to dissolve metals! Usually it consists of one part of hydrochloric acid (HCl) and three parts of nitric (HNO3). It is also permissible to add sulfuric acid (H2SO4) there. Imperial vodka looks like a yellow liquid, from which the unpleasant smell of chlorine and nitrogen oxides comes from.

Imperial vodka is remarkable in that it dissolves almost all metals, even such as gold and platinum, but at the same time, metals do not dissolve in any of the acids in its composition. Active substances capable of dissolving metals are born from a mixture of acids, during complex chemical reactions. However, there are metals that Royal Vodka is too tough for: rhodium, iridium and tantalum. Fluoroplast and some plastics are not soluble in aqua regia.

History of creation and name

Imperial vodka was created thanks to the research of alchemists, tireless in search of the legendary "philosopher's stone", which was supposed to turn any substance - into gold. They called gold “the king of metals”, respectively, a liquid that can dissolve it - they called it “the king of waters” (in Latin - aqua regia). But the Russian alchemists translated this name into their native language in a somewhat peculiar way - in their mouths “the king of the waters” became the “royal vodka”.

Alchemists learned how to make royal vodka even before it was discovered. In those days, the distillation of a mixture of nitrate, alum and vitriol was used to make this compound, adding there also.

Using aqua regia

Today, when no one is looking for a philosopher's stone, royal vodka is used as a reagent in chemical laboratories - for example, in the refining of gold and platinum. But most often, chemists need aqua regia as a reagent to produce chloride of various metals. Lovers use royal vodka in order to mine gold from.

It is important to remember that aqua regia retains its properties only if it contains chlorine, which, if you leave the vessel with the substance open, will quickly evaporate. During long-term storage of aqua regia, chlorine also gradually disappears, and the liquid ceases to dissolve the metals.
