Vedclass · Answer

(A) Amphoteric metals like $Zn$,$Be$,and $Al$ react with strong bases like $NaOH$ to produce hydrogen gas $(H_2)$ and their respective salts.For example:$Zn + 2NaOH \rightarrow Na_2ZnO_2 + H_2$$2Al + 2NaOH + 6H_2O \rightarrow 2Na[Al(OH)_4] + 3H_2$$Be + 2NaOH \rightarrow Na_2BeO_2 + H_2$However,$Mg$ is not amphoteric and does not react with $NaOH$ to evolve $H_2$ gas.

$H_2$ gas is not produced in which of the following reactions?
