Iodine is not an elemental substance. Iodine wine is iodine.
A solution formed by dissolving in alcohol, is.
A mixture. Elemental is pure. Thing.
-
No, it's an alcoholic solution of iodine. It's a mixture.
-
Iodine wine, which is an alcoholic solution of iodine element, is a mixture.
So, iodine wine is not a simple substance

The solutes of iodine wine are iodine and potassium iodide. 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.
Quality requirementsThe concentration of iodine tincture generally varies with the nature of the drug or medicinal material, unless otherwise specified, the iodine tincture containing highly toxic drugs is equivalent to 10 grams per 100 ml of the original drug or medicinal materials, and the other iodine tincture is equivalent to 20 grams of drugs or medicinal materials per 100 milliliters, and the active ingredients of iodine tincture containing highly toxic drugs should be adjusted according to the content or potency of the semi-finished product to meet the requirements of each iodine tincture.
When iodine tincture precipitates for a long time, the ethanol content can be measured or the precipitate can be filtered out and then adjusted to the specified standard for use.

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.

The solute of the bond in the iodine solution is iodine, and the solvent is alcohol. Iodine tincture, also known as iodine wine, is a reddish-brown liquid, the main components are iodine and potassium iodide. Iodine wine can kill bacteria, fungi, viruses, etc., and can be used for many bacterial, fungal, viral and other diseases.
Iodine wine is a commonly used disinfectant, and the main ingredients are iodide, water, and alcohol. It is iodine that plays a bactericidal role in iodine wine, not alcohol.
Alcohol is also a commonly used disinfectant, the common one being alcohol cotton balls, which are made from 75% alcohol and sterile cotton balls.
Hydrogen peroxide, also known as hydrogen peroxide, is a commonly used disinfectant, which is a colorless and transparent liquid, and when the surface of the manuscript pants is wiped on the wound, the surface is oxidized to white and bubbles.
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. >>>More
1. Iodine wine has a strong effect of killing pathogens, and iodine wine is made of iodine and potassium iodide, which is dissolved in the liquor type trapped essence solution. Iodine is a solid, and potassium iodide helps in the dissolution of iodine in alcohol. The iodine rent shortage liquor sold in the market has a concentration of 2%. >>>More
Let's correct it first, so that "cooking wine" instead of "iodine wine". >>>More
Elemental, because it is not a compound, it is not a valency! If you have to say that he is 0, it means that he is electrically neutral. Electrically neutral due to the fact that it is made of the same atom. >>>More
