Question

Explain why can alkali and alkaline earth metals not be obtained by chemical reduction method.​

Answer 1

Explanation:

Alkali and alkaline earth metals have high reduction potentials. Hence, they are very strong reducing agents. Hence, other reducing agents cannot reduce oxides or other compounds of alkali and alkaline earth metals. Hence, chemical reduction is not possible

Answer 2

$\huge\boxed{\fcolorbox{purple}{ink}{Answer}}$

Alkali and alkaline earth metals are themselves better recucing agents, and reducing agents better than alkali metals are not available. That is why these metals are not obtained by chemical reduction methods.
