Boric acid is an acid because its molecule

A

contains replacement `H^(+)` ion

B

gives up a proton

C

accepts `OH^(-)` from water releasing proton

D

combines with proton from water molecule

Text Solution

Verified by Experts

The correct Answer is:
C
Due to small size of B and presence of only six electrons I its valence shell, `B(OH)_(3)` accepts a `OH^(-)` from `H_(2)O` releasing a proton, i.e, option (c ) is correct.
