It's hard to imagine a chemistry lab.without special cones, test tubes, chemical reagents and so on. One of the dangerous, but necessary substances is crystalline iodine. What it is? Crystalline iodine is important for conducting various experiments, without which it is impossible to imagine the existence of any chemical laboratory. Although it is used in many industries, but still the priority area is pharmaceuticals and medicine.
Opening
Inquisitive and very attentive scientist B.As early as 1811, Courtois discovered that a plaque (substance unknown at that time) was formed on the walls of the boilers for the production of soda from algae. Then the scientist decided to take up this issue closely, and soon he received the very powder that, when heated, gave beautiful purple clouds of smoke.
At the same time, and published information about this new substance. Other scientists began to be interested in them. They gave him the name "iodine", which means "violet".
Rename
In the middle of the twentieth century, the well-known iodine, element No. 53 in the periodic table of the Periodic Table, denoted J, was renamed Iod, after which it was designated the letter I.
Despite this, he continues to be called iodine to this day: even in a pharmacy, on the labels of preparations containing this element, it is impossible to find the correct name of this substance.
What does a chemical look like?
Crystalline iodine is often referred to as iodine in the chemical nomenclature. These are small crystals with a metallic tint of an unusual color — something between gray and black.
As for the smell, it is sharp and characteristic.If you place the crystals at room temperature, they will have a dark purple color, and the luster will not be so pronounced. An interesting feature: crystalline iodine forms vapor when heated, and upon cooling, crystallization occurs immediately. In this case, such an aggregative state as a liquid is passed. Iodine is highly soluble in liquids, excluding water.
Where is the
Crystalline iodine has such a property asabsent-mindedness in nature. What does it mean? It can be found almost everywhere: in sea water, in living organisms and even in algae, for example, in the well-known sea kale. Iodine can also be found in very rare minerals that have been found in Italy.
As for the extraction of substances in industrial conditions, it is obtained from algae and oil drilling waters.
Crystalline iodine: application
It is used in medicine, chemistry. From iodine, which is in the form of a crystal, preparations are made not only for external use, but also for internal use.
Iodine in solution, as many are accustomed to itsee, contains only 5 mg of crystalline. For external use, it is used for many iodine ointments, alcohol solutions. If these drugs are used externally, they have an antiseptic, anti-inflammatory effect. The substance is used to treat wounds, wiping the surgeon's hands during the operation.
Application inside
In addition to external use, crystalline iodineused for oral administration, but certainly not in its pure form. Why is this necessary? To normalize the metabolism, to replenish the body with essential substances and vitamins. Also, with the consumption of iodine, the thyroid gland improves.
All familiar drug "Iodomarin" is recommended to be used by everyone without exception, since iodine is much in the body only among people living by the sea.
How to purchase
Crystalline iodine is very commonsubstance. It can be purchased at a pharmacy at an affordable price. If you did not find it in the pharmacy (which is extremely surprising), then you can order it in online stores. The Internet is filled with offers of good quality crystalline iodine sellers at affordable prices.
