Which of the following is an amphoteric hydroxide?
Sr(OH)2Sr(OH)_2Sr(OH)2
Ca(OH)2Ca(OH)_2Ca(OH)2
Mg(OH)2Mg(OH)_2Mg(OH)2
Be(OH)2Be(OH)_2Be(OH)2
Be(OH)2Be(OH)_2Be(OH)2 is amphoteric in nature, since it can react both with acid and base. Be(OH)2+2HCl⟶BeCl2+2H2OBe(OH)_2 + 2HCl \longrightarrow BeCl_2 + 2H_2OBe(OH)2+2HCl⟶BeCl2+2H2O; Be(OH)2+2NaOH⟶Na2[Be(OH)4]Be(OH)_2 + 2NaOH \longrightarrow Na_2[Be(OH)_4]Be(OH)2+2NaOH⟶Na2[Be(OH)4].
