They also contain one or more other elements, such as silicon, titanium, vanadium, chromium, manganese, cobalt, nickel, zirconium, molybdenum, and tungsten. Two other steel-like products are cast iron and wrought iron. Cast iron is an alloy of iron, carbon, and silicon. Wrought iron contains iron and any one or more of many other elements. In general, however, wrought iron tends to contain very little carbon. It would be impossible to list all uses of iron and steel products. In general, those products can be classified into categories: 1 automotive; 2 construction; 3 containers, packaging, and shipping; 4 machinery and industrial equipment; 5 rail transportation; 6 oil and gas industries; 7 electrical equipment; and 8 appliances and utensils.
For more information on specific kinds of steel alloys, see individual elements, such as titanium, vanadium, chromium, manganese, molybdenum, and tungsten. Some iron is made into compounds. The amount is very small compared to the amount used in steel and other iron alloys. Probably the fastest growing use of iron compounds is in water treatment systems.
The terms ferric and ferrous refer to two different forms in which iron occurs in compounds.
Some of the important iron compounds are:. Iron is of critical importance to plants, humans, and animals. It occurs in hemoglobin, a molecule that carries oxygen in the blood. Hemoglobin picks up oxygen in the lungs, and carries it to the cells. In the cells, oxygen is used to produce energy the body needs to survive, grow, and stay healthy. The U. Iron is available in a number of foods, including meat, eggs, and raisins. An iron deficiency lack of iron can cause serious health problems in humans. For instance, hemoglobin molecules may not form in sufficient numbers. Or they may lose the ability to carry oxygen.
If this occurs, a person develops a condition known as anemia. Anemia results in fatigue. Severe anemia can result in a lowered resistance to disease and an increase in heart and respiratory breathing problems.
Some forms of anemia can even cause death. Toggle navigation. Photo by: gyn Discovery and naming Ancient Egyptians had learned how to use iron before the First Dynasty, which began in about B.
For the sake of argument, we'll take the catalyst to be iron(II) ions. If you use iron(III) ions, the second of these reactions happens first. Hydroxide ions (from, say, sodium hydroxide solution) remove hydrogen ions from the water ligands attached to the iron ions. Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number It is a metal, that belongs to the.
Physical properties Iron is a silvery-white or grayish metal. The other two are nickel and cobalt Iron has a very high tensile strength. Chemical properties Iron is a very active metal. Occurrence in nature Iron is the fourth most abundant element in the Earth's crust. Isotopes There are four naturally occurring isotopes of iron, iron, iron, iron, and iron Extraction Iron goes through a number of stages between ore and final steel product.
Uses It would be impossible to list all uses of iron and steel products. Compounds Some iron is made into compounds. Some of the important iron compounds are: The U. Health effects Iron is of critical importance to plants, humans, and animals. Other articles you might like:. Follow City-Data.

User Contributions: 1. Thanks a lot and I mean it. We had science work and I was failing but what I really liked was that the definitions of complicated terms was mentioned.
That really helped me. Thanks again! This really helped for a molecule report I had to write on iron III oxide. However, it would be really helpful if there were a way to cite this website as a legitimate source. For example, there is not author or date of publication.
Maureen Drieberg. Thank you. I have now understood how iron works. When I was at school, most girls were considered as non-scientific beings. I have struggled with prejudice all my life and have had to fight, sacrifice and study to be where I am today. I now encourage all women who are interested to learn more about the opportunities that science can offer. Ayzawa Misaki. I have a question what's the element that react with iron make it no longer iron or make it decompose!!!?? Egere Ann. This has helped me in understandingg the chemistry of iron.
Now i can do my assignment with ease. Onesmo simon. Hi there , I would like to know if there are any other methods physically or chemically to extract iron from iron ore other than the blast furnace method. My daughter is working on school project about iron. The precise chemical structure of the iron gall ink pigment has recently been investigated by two researchers C. Wunderlich and C. Krekel and each has developed different theories on the structure of the colored compound. Wunderlich was able to form black crystals using Fe III Cl3 and gallic acid in a gel of sodium silicate.
He suggests that the iron reacts with the three hydroxyl groups of gallic acid and with the carboxyl group, creating a three dimensional structure. Wunderlich created these molecules using Fe III ions.
However, when iron gall ink is produced using iron sulfate, the ferrous tannate complex is formed with Fe II. Krekel has researched pigment formation using different metals under varying circumstances. He was able to create a black pigment which he examined using different analysis techniques mass spectrometry, infrared spectrometry and Mossbauer spectrometry.
His study suggests that the black pigment, instead of a iron gallic acid complex, is an iron pyrogallol complex. His research will be published in the proceedings of the meeting of specialists in Ludwigsburg.
An abstract of his results will be presented here.
