The role of iron in the human body is difficult to assess, because its surplus will lead to imminent diseases, and the lack is also undesirable. This element is responsible for the level of hemoglobin and is able to normalize the enzyme system. But if we take into account the chemical properties, the question of iron valence becomes quite interesting for any person. To understand the situation will require a detailed consideration of all the important nuances. In the article, this information will be laid out consistently, only so everyone will be able to discover something new.
What does the concept include
The property of chemical elements is quite clear, because they are all distinguished by permanence, the water formula, for example, contains 1 oxygen atom and 2 units of hydrogen. Other compounds are also arranged, valence is called the ability of the element atom to attach to itself a specific number of atoms of other elements. There are specimens with constant valence in the Mendeleev table, but some of them may be six valents, like sulfur and 4, it is about carbon. Ferrum also stands out a little bit from the list, it happens to be 2 and 3-valent. The formula of compounds is made by sequence of atoms in a molecule. If you find out the value of one of the elements, it's hard not to deal with the data about the other component of the chain.
Iron can be safely attributed to units with variables, values can fluctuate not only between 2 and 3, but also reach even six. Such studies are engaged in specialists in the industry of inorganic chemistry, but every person such knowledge is sure to come in handy. If we consider the mechanism briefly and take into account simple particles, this element is able to count 31 positions from the list, these are paragraphs from 4 to 7 periods of the Mendeleev table. As the serial number will gradually grow, the properties of the ferrum will change somewhat. In addition to the increase in the atomic radius, it will be possible to notice variable valence, this is due to the incompleteness of the sub-level. More likely to see more stable compounds with 2 and 3, and the most unreliable are four to six, but they are rare.
This iron has a pronounced black color, it occurs after the interaction of the connection with water. Experts note good compatibility with salt and nitric acid. To achieve a pure state of 2 valence oxide can after interaction with hydrogen at a temperature of 350 degrees, or the process will require heating up to 1000 degrees and carbon participation. Mining is due to a specific algorithm of actions that looks like this:
- 3 valent ferrum oxide is combined with carbon monoxide.
- The pure fossil is heated at low oxygen pressure.
- Using a vacuum environment, the oxalate is laid out.
- Reaching a temperature of 1000 degrees, pure iron interacts with oxides.
It is possible to determine the indicators of natural fossil with a solution, the reaction with red salt and alkalinity is able to tell a lot, namely to reveal valence with a score of 2. The result is responsible for a specific precipitation, which has a dark blue tint, with the second element will eventually be observed gray-green color, in both cases the result will be as accurate as possible. If the shade turns out to be dark brown, the iron can be safely considered 3 valent. This kind of fossil is often found in a powdery structure.
Considering details of a different type of connection
Ferrum with a value of 3 is also different in color, it will be red-brown, of the common names it is worth noting iron oxide, browning, red pigment, coloring for food and crocus. In nature, you can also find this substance, it is represented in the form of a mineral such as hematite. Such oxide with water will not interact, the only compounds will be lye and acids. Some building materials are quite successfully painted with this composition, here are:
- Cement mixtures.
- Sidewalk tiles.
- Floor coverings, including linoleum.
Iron participation in every human body
Without this component, people would not exist, because insufficient amount of ferrum will lead to such disastrous consequences as:
- Fatigue and hypersensitivity to cool.
- The skin will be dry.
- Brain activity will go down.
- Nails will lose their former strength.
- Digestive disorders.
- Hair can quickly gray and fall out.
Experts note that often unnecessary accumulations occur in the spleen, liver, kidneys and pancreas. To avoid the shortage, you should review your diet and necessarily eat such ingredients as: liver, buckwheat porridge, peanuts, white mushrooms, eggs, dogwood and more. It is impossible to neglect the lack of iron in the blood, because the lowering of hemoglobin will lead to more serious health problems.
