Vedclass · Answer

(C) Amphoteric hydroxides are those that can react with both acids and bases.$Al(OH)_3$ is amphoteric because it reacts with $HCl$ (acid) to form $AlCl_3$ and with $NaOH$ (base) to form $Na[Al(OH)_4]$.$Be(OH)_2$ is also amphoteric as it reacts with $HCl$ to form $BeCl_2$ and with $NaOH$ to form $Na_2[Be(OH)_4]$.Therefore,the pair $Al(OH)_3$ and $Be(OH)_2$ consists of amphoteric hydroxides.
