👉 Reoxidise in chemistry refers to a process by which an element is oxidised, or oxidises itself, to form another element. This can be achieved through various chemical reactions, such as combustion or reaction with other elements, and has applications in the industrial sector for producing various products. For instance, reoxidising iron (Fe) to iron(III) oxide (Fe2O3), an important compound used in the manufacturing of steel, would involve a process where iron reacts with oxygen gas
