Mercury, also known as "white", is a liquid metal at room temperature, and its acetate, scientific name is mercury acetate, has many chemical properties.
Mercury acetate is a covalent compound. Due to the special electronic structure of the outer layer of mercury ions, it is covalent with acetate. This structure makes mercury acetate soluble in organic solvents, such as slightly soluble in ethanol, ether, etc., and relatively small solubility in water.
It has strong oxidation, and mercury is in the + 2 valence state and has an electronic tendency. When encountering certain reducing substances, it is prone to redox reactions. If it encounters active metals, such as zinc, iron, etc., mercury ions will be reduced to mercury elementals, and active metals will be oxidized to corresponding ions. Taking zinc as an example, the reaction formula is: $Zn + Hg (CH_ {3} COO) _ {2} = Zn (CH_ {3} COO) _ {2} + Hg $.
Mercury acetate has significant hydrolysis, because acetic acid is a weak acid, it will undergo hydrolysis in water. $Hg (CH_ {3} COO) _ {2} + 2H_ {2} O\ rightleftharpoons Hg (OH) _ {2} + 2CH_ {3} COOH $, the generated mercury hydroxide is unstable and easily decomposes into mercury oxide and water.
When heated, the stability of mercury acetate is poor, and it will decompose to produce mercury vapor, carbon dioxide and other gaseous products. This decomposition process varies according to different conditions. Generally speaking, mercury elemental substances and carbon oxides will be formed when heated. Due to its mercury content, the decomposition products are more toxic.
Mercury acetate is chemically active and needs to be used and handled with extreme caution. Due to its toxicity and great harm to human body and the environment, the operation should follow strict safety regulations.

Borax is a commonly used medicinal stone, which has important uses in many fields such as medicine, alchemy, and alchemy.
In the field of medicine, borax can be used as a heat-clearing and detoxification agent. Its cold nature can clear the heat poison of coke, and it is quite effective for sore throat and mouth sores. As recorded in many ancient medical records, borax is often used in combination with other heat-clearing and swelling-reducing drugs, ground into a powder, and blown on the affected area to achieve the purpose of reducing swelling and pain, clearing away heat and detoxifying. If it is used to treat sore throat, it is often combined with borneol, Xuanming powder, etc., and blowing the throat can make the swelling and pain disappear quickly.
In alchemy, borax is also indispensable. In the process of alchemy by the ancients, borax can be used as a flux. Because borax can reduce the melting point of ore and other raw materials at high temperature, it makes various substances easier to melt and mix, and promotes the progress of chemical reactions, which helps to refine medicinal pills. Ancient alchemists through long-term practice, well aware of the characteristics of borax, skillfully used it in the alchemy process, hoping to refine pills with magical effects.
In the field of gold, borax also plays an important role. In the metallurgical process of gold, borax can help remove impurities in the ore. Borax can react with impurities such as silica in the ore to form slag, which is then separated from gold to improve the purity of gold. In ancient metallurgical technology, this method was widely used to help refine more pure gold and meet people's pursuit of gold quality.

The method of making sea nitric acid is to take saltpeter and sulfuric acid to heat together. The method is as follows:
Take a clean retort, make it of glass or porcelain, put saltpeter in it, and slowly inject sulfuric acid on it. Connect the neck of the retort with a long glass tube and introduce it into a glass bottle.
First heat the furnace, so that the retort is heated evenly. When saltpeter is mixed with sulfuric acid, a chemical reaction occurs. For saltpeter, potassium nitrate also interacts with sulfuric acid to form potassium sulfate and nitric acid. Nitric acid evaporates when heated, and is introduced into the glass bottle along the glass tube with the hot air. The outside of the bottle is drizzled with cold water, so that the nitric acid vapor is cooled and condenses into a liquid, which is to obtain nitric acid.
When operating randomly, be extra careful. Sulfuric acid is highly corrosive, and saltpeter is also an unusual thing. When the two meet, the reaction is violent. And nitric acid is also corrosive, and its steam is pungent, so it must be done in a well-ventilated place. All utensils used must be resistant to acid corrosion. If not handled properly, it may be dangerous to cause injury to people and destroy utensils. Therefore, anyone who practices this technique must know the method in detail and practice it cautiously, so that it will not be harmful. In this way, sea nitric acid can be obtained for various purposes, such as pharmaceuticals, metallurgy, etc., all rely on it.

Mercury is a highly toxic substance, and its acetate requires careful attention when storing and transporting it.
Choice of the first heavy container. When corrosion-resistant materials are preferred, such as glass, ceramics or specific plastics. Glass containers are chemically stable and do not react easily with mercury acetate, so attention should be paid to their fragility; ceramic containers also have good corrosion resistance; specific plastic containers, such as polytetrafluoroethylene materials, have good resistance to mercury acetate. Metal containers should not be used, because mercury acetate or chemical reactions with metals cause composition changes or container corrosion.
The second is storage environment. Should be placed in a cool, dry and well-ventilated place. Avoid direct sunlight, light or trigger chemical reactions such as the decomposition of mercury acetate. Excessive temperature will also accelerate its deterioration, and the ideal storage temperature should be maintained in a lower range. At the same time, ensure that the storage place is dry, because moisture or mercury acetate deliquescence will affect its quality and stability.
Further transportation links. Be sure to take protective measures to ensure that the container is tightly sealed to prevent leakage. The packaging should be solid and can withstand a certain external impact to prevent the container from being damaged during transportation. During transportation, keep away from heat sources, fire sources and other chemical dangerous goods to avoid dangerous reactions. In the event of a leak, emergency measures should be taken immediately, evacuate personnel, and use appropriate materials to absorb and clean it up to avoid greater harm caused by the diffusion of mercury acetate.
In short, the storage and transportation of mercury acetate, from container selection, environmental control to transportation protection, is all about safety and quality, and must not be taken lightly. It must be operated in strict accordance with regulations.

The situation of the sodium cyanide market is actually related to many factors and is intricate. This test is for you to analyze.
Sodium cyanide is widely used in various fields of chemical industry, such as metallurgy, electroplating and other industries, which are indispensable. Its market price often fluctuates with changes in supply and demand.
In the past, if the metallurgical industry was booming, the demand for sodium cyanide surged, and the supply was in short supply, the price would often rise. Due to the strong demand, merchants competed to buy, and the highest bidder got the price.
However, if the electroplating industry suffered a setback, the development slowed down, the demand for sodium cyanide was greatly reduced, and the market was oversupplied, the price would show a downward trend.
Furthermore, the price change of raw materials is also the key to affecting the market price of sodium cyanide. If the price of raw materials required for the production of sodium cyanide rises, the production cost increases, and the merchant must raise the price of sodium cyanide in order to ensure profitability. On the contrary, the price of raw materials drops, the cost decreases, and the price of sodium cyanide also decreases.
The impact of policies and regulations should not be underestimated. If the government strictly regulates the production, transportation and sales of sodium cyanide, and many restrictions are promulgated, some manufacturers may reduce production and stop production due to high compliance costs, and the market supply will decrease, and the price may rise.
The changes in the international market also affect the domestic sodium cyanide market. If overseas sodium cyanide production increases significantly and a large number of them flood into the domestic market, the supply will be sufficient, and the price may be suppressed. On the contrary, if there is a shortage of international supply, the domestic market price may rise as a result.
To sum up, the market price of sodium cyanide is affected by many factors such as demand, raw materials, policies, and international markets, and its market is constantly changing, which is difficult to hide. Businesses operating in it need to understand the situation of all parties in order to seek development.
