Bronsted and Lewis acid definitions?

Postby Daniel Rivas 3L » Tue Nov 28, 2017 4:26 pm

So in high school I learned to call Bronsted and Lewis acids strong and weak acids respectively. Are they the same thing? Also what differentiates a Bronsted (strong) and Lewis (weak) acid?

I think Bronsted acids and Lewis acids are just different by definitions. Bronsted acids are proton donators and Lewis acids are electron acceptors. I don't think they are related to strong or weak acids.

Are lewis acids and bases the same as bronsted? Or are they different types of acids and bases?

Whether or not something is an acid or base does not change no matter what definition you use, but the Bronsted/Lewis definitions focus on different characteristics. Bronsted acids donate protons while Bronsted bases accept them. Lewis acids accept electron pairs while Lewis bases donate them. However, an acid is still an acid and a base is still a base no matter what definition you look at.
