What is the name of fe3 po3 2?
If a metal is more reactive than carbon, other chemical reactions and processes must be used in its extraction. Certain metals, such as iron, can be only be reduced using carbon if they are heated to very high temperatures.
Removal of carbon: The still impure molten iron is mixed with scrap iron (from recycling) and oxygen is blown on to the mixture. The oxygen reacts with the remaining impurities to form various oxides. The carbon forms carbon monoxide. Since this is a gas it removes itself from the iron!
Rust from Iron (III) oxides forms due to high oxygen and water exposure resulting in red rust. Red rust is the result of heavy exposure to air and moisture, combined many times with a contaminate (salt). With red rust, there is uniform corrosion, most often from a very corrosive environment.
Why is rust red?
Uses. Iron(II) oxide is used as a pigment. It is FDA-approved for use in cosmetics and it is used in some tattoo inks. It can also be used as a phosphate remover from home aquaria.
Iron(II) phosphate, also ferrous phosphate, Fe3(PO4)2, is an iron salt of phosphoric acid….Iron(II) phosphate.
