The chemical properties of thallium and mercury bis (thallium acetate trihydrate) are particularly important. Thallium is a highly toxic metal element with active chemical properties and can show unique states in many chemical reactions. At room temperature, thallium easily interacts with oxygen in the air to gradually oxidize the surface layer of thallium. Although this oxide layer can prevent further oxidation of thallium to a certain extent, thallium can still be deeply oxidized when encountering strong oxidants, presenting high-valence compounds.
As for mercury, it is also a special metal. It is liquid in normal state and volatile. Although the chemical activity of mercury is weaker than that of some metals, it can also participate in various chemical reactions under certain conditions. In the system of thallium acetate trihydrate, mercury interacts with thallium and acetate ions to form unique chemical structures and properties.
In thallium acetate trihydrate, acetate ions are combined with thallium ions in their specific coordination mode, which gives the compound a certain stability. At the same time, water molecules also participate in it, or interact with thallium ions, or interact with acetate ions through hydrogen bonds, which affects the physical and chemical properties of the compound. Thallium-mercury bis (thallium acetate trihydrate) may be ionized in solution to produce corresponding ions. The behavior and reactivity of ions are also affected by factors such as temperature and pH in the surrounding environment. In case of some specific reagents, thallium-mercury bis (thallium acetate trihydrate) can undergo double decomposition reaction, redox reaction, etc., to form new compounds and exhibit rich chemical changes.

Arsenic (arsenic trioxide) is also a highly toxic thing. It is often used in a fresh way. It is covered by its severe toxicity, causing more harm and less benefit. In ancient times, there were also two ways to use it.
One of them may be involved in medicine. Ancient healers were well aware of the toxicity of arsenic, but they used its principle of "fighting poison with poison" to deal with some serious diseases, or tried it. Such as treating scabies and sores, after being processed, it can be used as medicine to poison all kinds of evil insects and evil filth, so that the skin can recover. However, this usage requires extreme caution. If the dose is slightly exceeded, it will not cause disaster and cause death.
Second, in the art of alchemy, or see traces of arsenic. The ancient alchemists were obsessed with alchemy in order to seek the medicine of immortality, and arsenic was occasionally used by them. They thought that after various refinements, they could dissolve the poison of arsenic and obtain a miraculous elixir. However, these are all absurd and unreasonable ideas, which often cause poisoning and death to those who take it.
Third, in the matter of punishment, there are also those who use arsenic as a means. Because of its poison, it can quickly cause death, so it is used in capital punishment, or the offender is killed by this poison. However, this is also a cruel act, not suitable for use in prosperous times.
As for the livelihood of ordinary people, arsenic is never used for daily use. Because of its strong toxicity, it can kill anyone who touches it or eats it, and everyone avoids it. It is the way of arsenic, which is more about sinister and taboo, and an unusual and beneficial technique. It is really important to stay away from it, and do not take chances to involve this poison.

The method of making the best of the best (Sanxiang acetic acid paste)

The former















The first to get the best of the best of the best, it must be the best of the land. Such as taking the grass of the southern mountains, the fragrant wood of the northern mountains, this kind of wood, the quality and strength.
And, with the water of the sea, soak the wood in the After soaking for 7 days, depending on the nature of the raw material, or three days, or five days, until it absorbs moisture, it is appropriate to cook.
Put it in the kettle and fry slowly. The size of the fire is the most important, not too fierce, or it is afraid of burning; not too weak, and the pressure will be released. After frying, you need to mix it well, so that the raw material is evenly damaged. Wait for the liquid to be amber, and then stop.
Then add the fried liquid into the cloth sac, take the juice, and remove the dross. The obtained juice, re-enter the kettle, and add the amount of honey. Honey is the honey of hundreds of flowers, sweet and positive. Boil slowly over low heat, so that the honey juice is mixed, until the paste is thick, and can be placed on the grate without burning, and the paste (Sanxiang acetic acid paste) can be made.
The paste made by the paste is stored in a porcelain bottle, sealed and properly stored. With the paste, take the amount of milk to treat the patient, or take it, apply it according to the disease, and it will have its own good effect. This method is used from generation to generation, carefully guarded, and dare not make mistakes. Because of the success of the paste, human life will be damaged.

Arsenic, that is, arsenic trioxide. It is highly toxic, and many things need to be careful during use.
First, the use of arsenic must be done with extreme rigor. There needs to be a precise measuring tool, and there must be no mistake at all. Cover because of its toxicity to the extreme, a slight excess, it will harm life. Like those who are good at using poison in ancient times, the use of arsenic is also like walking into an abyss, like walking on thin ice, to ensure that the dosage is accurate, and its purpose can be achieved without getting out of control.
Second, the preservation of arsenic must be kept in a secret and dry place. This medicine is extremely susceptible to moisture and deterioration. If it is not stored properly, the power of the medicine may change, and it may cause leakage, endangering others. In the past, when doctors hid arsenic, they had to use a special container, sealed properly, and hidden in a secret room to prevent others from accidentally touching it.
Third, when using arsenic, the choice of environment is also crucial. When operating in a well-ventilated place, it must not be in a small, closed place, so as to avoid the dust mist of arsenic, inhalation in the body, and poisoning. And there must be no unrelated people around to prevent accidental contamination.
Fourth, after applying the medicine, the utensils used must be properly disposed of. Do not discard at will to prevent others from accidentally touching. When buried deep or destroyed by special methods to ensure that arsenic does not remain in the world, and the consequences are endless.
Fifth, the person applying the medicine must not slack off his own protection. Wear protective clothing, gloves, etc. to avoid direct contact with the skin. If you accidentally touch it, you should immediately rinse with plenty of water to prevent toxicity from penetrating into the skin.
Although arsenic is poisonous, if used properly, it can also be used for medicine, insecticides, etc. However, in the process of use, every step is related to life and death, and there must be no slack. You must treat it with caution and awe, so as to be safe.

Alas! If you ask about the market price range of arsenic double (that is, arsenic trioxide), although I have not personally dealt with the market changes, I have heard a little about it.
Arsenic is also a highly toxic thing, which can be easily bought and sold by very people. In today's world, the national law strictly prohibits its private trading, and it is strictly controlled by the official family. It is mostly used in specific industries, pharmaceutical research and development and other fields. Unusual goods can circulate freely.
However, if the price is strongly discussed, it varies greatly due to different uses, purity, procurement channels, etc. For industrial uses, if the purity is average, according to some rumors in the past, the price may be thousands of yuan per ton. However, this price is not constant, and fluctuates with many factors such as market supply and demand, raw material costs, and difficulty in manufacturing processes.
If used in pharmaceutical research and development, the purity requirements for it are extremely high, and the price will also increase significantly. The higher the purity of the cover, the more difficult it is to make, and the higher the cost, the price may range from tens or even hundreds of yuan per gram.
It needs to be made clear that this is a rough guess, and regardless of the strict laws that must be followed when buying and selling this thing, only in terms of market conditions, it is also changing rapidly, and it is difficult to accurately say the exact price. Even with this price, you should not set foot in the transaction at will, so as to violate the prohibition of national laws and cause harm to yourself.
