Acids/Bases and Lewis Acids/Bases

[Matia Kim 1B]

Why is an acid and base about the donor and acceptor of protons whereas Lewis acids and base is about the donor and acceptor of electron pairs?

[Garrett Dahn 1I]

I'd imagine the idea of an acid and a base in chemistry has to do with an acid being the acceptor and the base being the donor -- Gilbert Lewis' work was related specifically to electron behavior. I'm pretty sure this just has to do with Lewis' namesake and the fact that acids are known to be acceptors and bases are known to be donors.

Hope this helps!

I think it has to do with different ways scientists classified acids and bases. I think they're just alternate ways to define them based on their properties.
