Boric acid is an acid because its molecule
contains replaceable H+ ion
gives up a proton
accepts OH- from water releasing proton
combines with proton from water molecule
As we discussed in the concept
Boric Acid as Lewis Acid -
Weak monobasic acid. Does not liberate hydrogen ion but accepts a hydroxyl ion.
- wherein
Boric acid is a lewis acid which accept OH-

contains replaceable H+ ion
This solution is incorrect
Option 2)
gives up a proton
This solution is incorrect
Option 3)
accepts OH- from water releasing proton
This solution is correct
Option 4)
combines with proton from water molecule
This solution is incorrect
