Acid but acidity is not due to its disassociation

Postby ariellasarkissian_3H » Tue Dec 04, 2018 8:06 pm

When Boron accepts electron pairs in the form of OH- from water, its acidity is not due to its disassociation. Can someone please explain the concept behind this? Thank you!

When Boron accepts lone pairs from water in the form of OH-, it is acting as a Lewis acid. After all, a Lewis acid is defined as an acid which accepts lone pairs.

Rather than being a Bronsted acid which donates protons, it is a Lewis acid that accepts electron pairs.
