Iodine is a vital trace element that is extremely rare in nature. We all know about the existence of iodine, we often use it as an antiseptic. But few of us think about the broader significance of iodine in human life.
After all, iodine https://chemist.eu/catalog/chemical-reagents/iodine-999-cas-7553-56-2 is an element that is minimal in its quantitative content, but very important for the stable functioning of the human body.
Its deficiency gives rise to various kinds of diseases and is often associated with a small intake of products containing iodine.
Therefore, my work was devoted not only to the study of such important theoretical material on the topic, but also to the qualitative detection of iodine in food products, so that we could know exactly which of them contain the most iodine.
Iodine is considered one of the rare elements: its average content in the earth’s crust is 0.00004% by mass.
However, despite the fact that it is not among the most common elements, it is very dispersed in nature, so it is present almost everywhere. Most of the iodine (namely, its iodides) is found in sea water.
Its content varies between 20-30 mg per ton of water. It is also observed in marine organisms (animal and non-animal origin). So, sea kale of all food products is famous for its highest content. In nature, iodine is found in the form of minerals.
The abundance of iodine’s own minerals is very low, so finding minerals such as lautarite and iodargyrite is a very rare occurrence. Iodine is found in oil drilling waters.
Chemical properties and use in reactions
Free iodine exhibits extremely high chemical activity. It interacts with almost all simple substances. The reactions of the combination of iodine with metals proceed especially quickly and with the release of a large amount of heat.
It reacts with hydrogen only when heated sufficiently and not completely, since the reverse reaction begins to take place – the decomposition of hydrogen iodine:
H2 + I2 = 2HI – 53.1 kJ
It dissolves in iodide solutions, forming unstable complexes. It disproportionates with alkalis, forming iodides and hypoiodites. Nitric acid is oxidized to iodic acid.
If hydrogen sulfide water (an aqueous solution of H2S) is added to a yellowish aqueous solution of iodine, the liquid becomes discolored and becomes cloudy from the released sulfur:
H2S + I2 = S + 2HI
In compounds, it exhibits oxidation states -1, +1, +3, +5, +7.
The best variant is to buy iodine cas 7553-56-2.
Where to buy high-quality iodine?
Choosing iodine at an affordable price can be a complex process. But don’t worry. Here are some tips to help you choose iodine at an affordable price:
1. Check the quality

4. Check Support
When choosing iodine, it is important to check for support. Check if the manufacturer offers post-purchase support. This will help you get help if needed.
We all know iodine. Each of us has an alcohol solution of iodine in the home first-aid kit, which is used as an antiseptic. Drying tissues, it does an excellent job of treating scratches and disinfecting wounds.
Another case of human use of iodine is the need to stimulate blood flow to soft tissues. Such a need often arises with bruises and sprains, when an iodine mesh is applied to the surface of the skin.
However, besides this, iodine also plays an important biological role, which should be considered in more detail!
