Q. Choose the weak monobasic acid, among the following

KEAMKEAM 2012The p-Block Elements

Solution:

$H _{3} BO _{3}$ is a weak Lewis monobasic acid, because it can only accept a pair of electron. None of its hydrogens are ionisable.

Note $H _{3} PO _{3}$ is a dibasic acid, $H _{3} PO _{4}$ is a tribasic acid, $HNO _{3}$ is a strong monobasic acid and $H _{4} P _{2} O _{7}$ is a tetrabasic acid.
