It's hard to imagine a chemical laboratory 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, pharmaceuticals and medicine are still a priority.
Opening
The inquisitive and very attentive scientist B. Courtois discovered back in 1811 that plaque (a substance unknown at that time) formed on the walls of boilers for producing soda from algae. Then the scientist decided to deal with this issue closely, and soon he received the same powder, which, when heated, gave beautiful purple puffs of smoke.
At the same time, information about this new substance was published. Other scientists began to take an interest in him. They gave him the name "iodine", which means "violet" in translation.
Rename
In the middle of the twentieth century, the well-known iodine, element No. 53 in the periodic table of the periodic table, denoted by J, was renamed Iodine, afterwhy it began to be denoted by the letter I.
Despite this, it continues to be called iodine to this day: even in a pharmacy, on the labels of preparations containing this element, you cannot find the correct name of this substance.
Looks like, chemical properties
Crystalline iodine is often referred to in chemical nomenclature as simply iodine. These are small crystals with a metallic sheen 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 brilliance will not be as pronounced. An interesting feature: when heated, crystalline iodine forms steam, and when cooled, crystallization occurs immediately. In this case, such an aggregate state as a liquid is skipped. Iodine dissolves well in liquids, excluding water.
Where is contained
Crystallic iodine has such a property as distraction 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 seaweed. Iodine can also be found in very rare minerals found in Italy.
As for the extraction of the substance in industrial conditions, it is obtained from seaweed and oil drilling waters.
Crystal iodine: application
It is used in medicine, chemistry. From iodine, which is precisely in the form of a crystal, preparations are made not only for externaluse, but also for internal use.
Iodine in dissolved form, as many are accustomed to seeing it, 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. A substance is used to treat wounds, wipe the hands of the surgeon during the operation.
Internal use
In addition to external use, crystalline iodine is also used for oral administration, but of course not in its pure form. Why is this needed? To normalize metabolism, to replenish the body with essential substances and vitamins. Also, with the consumption of iodine, the functioning of the thyroid gland improves.
The well-known drug "Iodomarin" is recommended for everyone without exception, since only people living by the sea have a lot of iodine in the body.
How to purchase
Crystal iodine is a very common substance. It can be bought at a pharmacy at an affordable price. If you did not find it in a pharmacy (which is extremely surprising), then you can order it in online stores. The Internet is filled with sellers of good quality crystalline iodine at affordable prices.
