Explain why alkali and alkaline earth metals cannot be obtained by chemical reduction methods?
(N/A) In the process of chemical reduction,metal oxides are reduced using a stronger reducing agent.
Alkali metals and alkaline earth metals are themselves among the strongest reducing agents.
Since there are no available reducing agents stronger than these metals,their oxides cannot be reduced to metals by chemical reduction.
Therefore,these metals are typically obtained by the electrolytic reduction of their fused salts.
