Diiodozinc

Zinc iodide (zinc iodide) is a chemical substance. Its properties are numerous. At room temperature, zinc iodide is a white crystal with a hard and brittle texture, like fine powder or granules. Its appearance is quite ordinary, but its properties are different.
Zinc iodide is very soluble in water, and when it enters water, it melts quickly like ice and snow in the warm sun, forming a clear liquid. Its aqueous solution is neutral, not corrosive as acid, nor caustic as alkali, and is quite peaceful. This liquid can be used as a mediator in many chemical experiments and industrial processes, participating in many reactions.
Zinc iodide is also soluble in organic solvents, such as ethanol, ether, etc., and can be melted with it. This property makes it quite useful in the field of organic synthesis, which can assist in the synthesis and transformation of compounds.
Furthermore, zinc iodide is hygroscopic. In a humid environment, such as a sponge, it is easy to absorb water vapor in the air and cause its own deliquescence. Therefore, it needs to be stored in a dry place to avoid its deterioration.
Under the action of heat, zinc iodide can decompose. When heated deeper, its structure gradually disperses, decomposing to produce iodine and zinc elementals or other compounds. This reaction can be used to produce zinc or iodine in a specific chemical process.
And zinc iodide is also unstable under light. Light can cause its chemical changes, or cause gradual changes in color, or change the composition. It is also necessary to avoid light for survival, and it is better to hide in a dark room or use a shading device. This is the chemical characteristic of zinc iodide, which is useful in chemical industry, medicine, and scientific research. It should not be underestimated.

Zinc iodide is often synthesized by chemical synthesis. The method is as follows:
Zinc is combined with iodine phase, and zinc powder is gradually added to the iodine container. When iodine encounters zinc, it reacts and emits heat and light. The reaction formula is: Zn + I ³ → ZnI ³. This way is also simple and direct, and pure zinc iodide can be obtained.
Or it is obtained by reacting zinc oxide with hydroiodic acid. Take zinc oxide, slowly add it to the solution of hydroiodic acid, and the two react in phase to obtain a solution of zinc iodide. The reaction formula is: ZnO + 2HI → ZnI ³ + H2O O. After that, if you want to obtain solid zinc iodide, you can evaporate and concentrate the solution to gradually lose water, and then cool and crystallize to obtain the solid zinc iodide.
There are also those who use zinc carbonate and hydroiodic acid as raw materials. Zinc carbonate is mixed with hydroiodic acid and reacts to escape carbon dioxide gas, and at the same time generate a zinc iodide solution. The reaction formula is: ZnCO 🥰 + 2HI → ZnI 🥰 + H 🥰 O + CO 🥰 ↑. Follow-up treatment, such as using zinc oxide as raw material, evaporates, concentrates, cools and crystallizes to obtain a pure zinc iodide solid.

The method of making diiodine zinc has been known in ancient times. The method is as follows:
Take zinc first, and choose the pure one as the best. The color of zinc is blue and white, and the quality is firm and brittle. Take an appropriate amount of zinc, wash it with water, remove its dust, and then dry it with a cloth.
Prepare iodine for the second time. Iodine is a purple-black crystal, with a strong smell. When taking iodine, it is advisable to be careful to prevent it from hurting your hands and nose.
Put the net zinc in a porcelain dish and slowly add iodine. When iodine meets zinc, it changes. At this time, it can be seen that it is slightly hot, and there is purple gas rising. This is the volatilization of iodine, which is also a sign of reaction.
In order to promote its reaction speed and completeness, It should not be too hot, for fear of damaging its quality. Slow down the heat over low heat, and add stirring from time to time, so that the zinc and iodine are evenly combined.
When the reaction is completed, what is stored in the dish is zinc diiodide. Its color or yellowish, like powder. When cold, store in a bottle, sealed to prevent it from getting wet and mixing with other things.
To make this zinc diiodide, the procedures must be followed, and every step must not be ignored. The amount of medication, the degree of heat, and the order of operation are all about success or failure. In this way, pure zinc iodide can be obtained.

Zinc iodide is also an important thing to be melted. There is something to be careful about hiding it and losing it.
When storing zinc iodide, the purity of its quality is the first priority. It is necessary to choose clean and dry utensils to prevent them from being dyed by other things and invaded by moisture. Cover zinc iodide is sensitive, and it is easy to deliquescence when wet, causing its qualitative change and losing its original use. Therefore, the place to hide should be constantly dry and transparent, and the temperature should not be passed, avoiding direct sunlight to prevent its decomposition.
When losing, be sure to follow the regulations. The packaging must be firm and tight to prevent it from leaking out. When handling, be careful not to break the utensils. If zinc iodide leaks and clears quickly, it will avoid contact with human skin and eyes. Because of its thorny nature, it will hurt when touched. Operators must also take appropriate protection, such as gloves, eyepieces, and masks, to protect themselves.
Furthermore, when connecting with zinc iodide, appropriate materials should be selected. Do not use those that are easy to deal with, such as certain metals, to prevent chemical changes.
When storing and transporting zinc iodide, it is necessary to be careful and follow the rules to ensure its quality and safety and avoid disasters.

"Tiangong Kaiwu" is an ancient scientific and technological book. It describes all kinds of craftsmanship in ancient and elegant languages. However, today's question "What is the impact of diiodine zinc on the environment and human body", I should answer it in an ancient way.
Diiodine zinc is also a chemical quality. Between the environment, its impact is quite complicated. If you are in nature, in contact with water or moisture, you may cause chemical changes and produce new substances. This new substance may be corrosive and damage the surrounding objects, such as earth, rocks, and grass. It may be in the soil, or change the nature of the soil, making fertility easier and hindering the growth and life of plants. In the water body, it may also disturb the aquatic ecology, harming the genus of fish, shrimp and algae, and causing ecological imbalance in water.
As for the human body, the effects of diiodine zinc should not be underestimated. If it enters the body through breathing, its particles may stab at the respiratory tract, causing cough and asthma. Over time, it will hurt the lungs and the function of the lungs will gradually weaken. If it comes into contact with the skin, or causes skin sensitivity, redness, swelling, and itching. If ingested carelessly, it is particularly harmful to the stomach and intestines, causing abdominal pain, vomiting, and even life-threatening. It may be stored in the body, damaging the viscera, such as the liver, kidneys, and other organs, disrupting its metabolism and harming human health. Therefore, the use and disposal of diiodine zinc should be used with caution to prevent it from harming the environment and human body.
