name two bases which are not alkali but dissolve in strong alkali

Open in App

Solution

The name of the bases are Zn(OH)₂ and Al(OH)₂
These bases are not alkali because they do not dissolve in water but they dissolve in strong alkali.
Zn(OH)₂ + 2KOH $\to$ K₂ZnO₂ + H₂O
Al(OH)₃+NaOH --> NaAlO₂+2H₂O
