When copper is heated with iron oxide, a redox reaction occurs, leading to the formation of copper oxide and iron. This process is a type of displacement reaction where copper, being more reactive than iron, displaces iron from its oxide. The reaction formula is: Cu + Fe2O3 -> CuO + 2Fe. This reaction is an example of the thermite reaction, albeit not the traditional aluminum-iron oxide reaction used for welding. It demonstrates the principle of reactivity in metals, where a metal with higher reactivity displaces a less reactive metal from its compound. Such reactions are exothermic, releasing heat, which makes the process sustain itself once initiated. This principle has practical applications in extracting metals from their oxides and in materials science.

La soda cáustica, conocida también como hidróxido de sodio o lejía, es un compuesto químico altamente corrosivo utilizado en diversas aplicaciones, desde la limpieza hasta la fabricación de jabón. Para su uso seguro, es crucial seguir ciertas medidas de precaución: siempre utilizar equipo de protección personal, como guantes y gafas de seguridad, para evitar quemaduras en la piel o daños en los ojos. Es recomendable disolver la soda cáustica en agua, no al revés, para prevenir reacciones descontroladas. La mezcla debe realizarse en un área bien ventilada, evitando inhalaciones peligrosas. Dado su poder corrosivo, úsela con moderación y siguiendo las indicaciones específicas para cada uso, ya sea desatascar tuberías, hacer jabón casero, o cualquier otra aplicación. Su manejo incorrecto puede causar daños irreparables, por lo que la información y prudencia son fundamentales al utilizar este producto.
