MCQ
Boric acid is an acid because its molecule.
- AContains replaceable $H^+$ ion.
- BGives up a proton.
- ✓Accepts $OH^-$ from water releasing proton.
- DCombines with proton from water molecule.
✓
Answer
Correct option: C.
Accepts $OH^-$ from water releasing proton.
Because of the small size of boron atom and presence of only six electrons in its valence shell, $\ce{B(OH)_3}$ accepts a pair of electrons from $\ce{OH^-}$ ion of $\ce{H_2O}$, releasing a proton.
