Question

Quizplus · Accepted Answer

Al(OH)₃ is an aluminum hydroxide compound with amphoteric properties, meaning it can act as both an acid and a base. At low pH (acidic conditions), the compound will dissolve due to protonation of the surface hydroxyl groups. At neutral pH, the compound will be relatively insoluble due to precipitation of the undissociated form. At high pH (basic conditions), the compound will dissolve due to deprotonation of the surface hydroxyl groups. Therefore, the solubility of Al(OH)₃ is pH-dependent and the best choice is A.
