Which of the following is acidic in nature ?A. `Be(OH)_(2)`B. `Mg(OH)_(2)`C. `Al(OH)_(3)`D. `B(OH)_(3)`

Answer» Correct Answer - D
`Mg(OH)_(2)` is a weak base , `Be(OH)_(2)` and `Al(OH)_(3)` are amphoteric in nature. `B(OH)_(3)` can accept one hydroxyl ion from water `(H_(2)O)` and proton is released. Thus, it acts as a Lewis acid.
`B(OH)_(3) + 2H_(2)O hArr [B(OH)_(4)]^(Ө) + H_(3)O^(oplus)`.
