Chemistry - Redox Reactions Question with Solution | TestHub

In this process Al is oxidized to ${\mathrm{Al}}^{3+}$ and $2{\mathrm{OH}}^{-}$ions are reduced to ${\mathrm{O}}^{2-}$ and $H_2$. So it is a redox reaction. The salt ${\mathrm{NaAlO}}_2$ is formed only after the redox process. So the entire process cannot be considered as acid-base reaction. Acid base reaction is just one step in the entire process
