1.	Which of the following is incorrect for `H_(3)BO_(3)`A. It is a strong tribasic acidB. It is prepared by acidifying an aqeous solution of boraxC. It has a layer structure in which planar `BO_(3)` units are joined by hydrogen bondsD. It does not act as proton donor but acts as a Lewis acid by accpeting hydroxyl ion
Answer» Correct Answer - A Boric acid `(H_(3)BO_(3))` is a weak monobasic acid with `K_(a) = 1.0 xx 10^(-9)`. It may be noted that boric acid does not act as a protonic acid (i.e, proton donor) but behaves s a Lewis acid by accepting a pair of electrons from `OH^(-)` ion. `B(OH)_(3) + 2H - O - H rarr [B(OH)_(4)]^(-) + H_(3)O^(+)`
