A)With conc. aq. NaOH, its suspension dissolves.
B)With conc. aq. HCl, its suspension dissolves.

Quizplus · Accepted Answer

An amphoteric hydroxide can react with both acids and bases. Therefore, it can dissolve in both concentrated sodium hydroxide and concentrated hydrochloric acid, leading to a clear solution rather than a precipitate. Thus, the behavior described in option E is the most appropriate for an amphoteric hydroxide.
