Show Hint
Boric acid (H$_3$BO$_3$) is a very unusual acid. It's a Lewis acid, not a Br��nsted-Lowry acid, as it accepts an OH$^-$ ion from water rather than donating its own proton. Remember its weak, monobasic nature and its characteristic layered structure in the solid state due to hydrogen bonding.
