Orthoboric acid `(H_(3)BO_(3))` commonly known as boric acid behaves as a
A. strong monobasic acid
B. weak tribasic acid
C. weak dibasic acid
D. very weak monobasic acid
A. strong monobasic acid
B. weak tribasic acid
C. weak dibasic acid
D. very weak monobasic acid
Correct Answer – D
`B(OH)_(3)+2H_(2)O hArr H_(3)O^(+) + [B(OH)_(4)]^(-)` , `pK_(a) = 9.25`
It does not donate protons like most inorganic acids but rather it accepts `OH^(-)`.
