How can metal like na and k be reduced
Web11 de dez. de 2024 · Carbon can be used to extract metals from some metal oxides. • A metal can either be reduced or oxidised in a reaction. • Reduction occurs when a metal in a compound loses oxygen, to form the elemental metal. • Oxidation occurs when a metal (or carbon) gains oxygen, to form an oxide compound.
