Metal oxides are reduced to corresponding metals by using suitable reducing agents such as carbon. For example, when zinc oxide is heated with carbon, it is reduced to metallic zinc.
Metal oxides are reduced to corresponding metals through various methods, primarily involving the addition of electrons to the metal cations. Common reduction methods include:
1. Thermal Reduction: Heating metal oxides with a reducing agent (e.g., carbon) at high temperatures.
2. Electrolysis: Applying an electric current to a molten metal oxide or its aqueous solution to drive the reduction reaction.
3. Chemical Reduction: Using chemical agents like hydrogen (Hâ‚‚) or a metal (e.g., aluminum) to directly reduce metal oxides.
These methods aim to provide electrons to the metal cations in the oxide, allowing them to gain electrons and be reduced to their elemental metal form.
