Propiedades: polvo negro; p.e 5,7; p.f. 1420°C; insoluble en agua, soluble en ácidos. Obtención: preparado del oxalato por calentamiento, pero el producto suele contener algo de óxido férrico. Peligros: Tolerancia (como humo); 10mg por metro cúbico de aire. Precauciones de transporte: (CG) peligroso cuando está caliente. 5, record 1, Spanish, - %C3%B3xido%20ferroso
Record number: 1, Textual support number: 1 CONT
Según sean sus valencias, el hierro da dos familias de compuestos: compuestos ferrosos [...] si el hierro es bivalente; compuestos férricos [...] si es trivalente. El óxido férrico o sesquióxido constituye el colcótar. El óxido ferroso o protóxido FeO se obtiene por reducción del anterior. 6, record 1, Spanish, - %C3%B3xido%20ferroso
Record number: 1, Textual support number: 2 CONT
El óxido ferroso se obtiene calentando el oxalato ferroso en ausencia de aire [...] Es inestable incluso a temperatura ambiente; al calor, se descompone rápidamente en hierro y Fe3[subíndice]O4[subíndice]. 7, record 1, Spanish, - %C3%B3xido%20ferroso
