What is the chemical formula of iodine? Solut in iodine chemical formula?

You should still be in junior high school, your chemistry teacher said this in order not to confuse you, in fact, these elements are not all composed of atoms, but also molecules, but rare gases and metals must be composed of atoms, some of the non-metals are atoms, some are molecules, such as sulfur, carbon can be composed of atoms but can also be composed of molecules composed of multiple atoms, and halogens are the iodine you talked about, as well as fluorine and chlorine.

Bromine is certainly composed of diatomic molecules.

Iodine. i2

Silicon. SI diamond. c

Red (white) phosphorus. p-sulfur powder.

S fluorine. Cl2 potassium oxide.

KCl sodium oxide.

Na2O calcium oxide. cao

The chemical formula is C2 H5 OH.

Iodine wine is an ethanol solution of iodine and potassium iodide, also known as iodine tincture. Therefore, the solutes of iodine wine are iodine and potassium iodide, and the solvent is ethanol.

Iodine wine is a reddish-brown liquid, which belongs to the halogen class of disinfection and antiseptic drugs. Because it has the active gene of oxidative destruction of pathogen plasma protein, and combines with the amino group of the protein to denature and precipitate, it has a strong bactericidal effect. Therefore, iodine is often used for wound disinfection.

Iodine in iodine wine is a solute and the chemical formula is i2. Iodine wine is a mixture of iodine and ethanol, the color is brownish-red, it has the effect of disinfection and sterilization, can kill fungi, bacteria and pathogens. **After the abrasion, you can use some iodine wine to disinfect, which can prevent infection and help the recovery of the wound, clean the wound site before using iodine wine, and then use a medical cotton swab dipped in iodine wine to disinfect the area.

Precautions for using iodine wine1. Patients do not use iodine in a large area to avoid the absorption of a large amount of iodine, resulting in iodine poisoning.

2. Iodine wine is generally not used for ulcerated **.

3. Patients with iodine allergy are prohibited from using it.

4. Iodine wine should not be applied at the same time as red medicine, so as to avoid iodine mercury and corrosion.

5. The storage time of iodine should not be too long.

The chemical formula of iodine element is i. Iodine is a purple-black shiny flake crystal with atomic number 53, and the isotope present in nature is 74 neutrons of iodine in the year of the French pharmacist Coutva first discovered elemental iodine. Elemental iodine is purple-black crystal, easy to sublimate, and easy to condense after sublimation.

Toxic and corrosive.

The discovery of iodine

As far back as the 4th century B.C., in the Zhuangzi of China, there is a record of gall disease, which is now iodine deficiency disease. Among them, Jin Gehong (4th century AD) first used the wine of seaweed to soak the **gall disease; Sui Chao Yuanfang (7th century AD) put forward the theory that gall disease is related to water and earth; Tang Sun Simiao and Wang Tao (8th century AD) expanded the use of kelp to ** gall disease. It was only in the 12th century A.D. that seaweed ** goiter began to be used abroad, about 800 years later than in China.

After centuries of life practice and research on iodine, iodine was first isolated from seaweed ash in 1813 by the French courtois; It was later named iodine by Guy Lussac; In 1820, Coindet recommended iodine preparations for the prevention and treatment of goiter; In 1896, Baumann first confirmed that the thyroid gland has the function of polyiodine, and isolated iodine from the thyroid gland.

On the coasts of France, Ireland and Scotland, marine plants are hit by waves and tides and drift to the shallows in the spring when the waves and waves are blowing. At low tide, the apothecary Courtois often visits those places to collect blackhorn, kelp and other algae plants. After returning home, the collected plants are piled up, slowly burned into ashes, and then impregnated with water, filtered, and clarified to obtain a plant leaching solution.
