The manufacturing of iron from ironore involves the process of
-
- Oxidation
- Reduction
- Electrolysis
- Fractional distillation
- Oxidation
Correct Option: B
Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as hematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions. Both carbon and carbon monoxide are used in the reduction of the iron oxide (Fe2O3) to give iron.
2Fe2O3 + 3C → 4Fe + 3CO2
Fe2O3 + 3CO → 2Fe + 3CO2
