bronsted vs lewis

[Sophia Dinh 1D]

What is the difference between bronsted and lewis acid and bases and which is more common?

[Petrina Kan 2I]

Bronsted and Lewis are simply definitions of how to describe an acid or a base. A Bronsted acid is a proton donor while a Lewis acid accepts an electron pair. It just depends on how you look at it. In high school, I was taught that we generally use the Bronsted definition more so perhaps that one is more common.

[Jamie Lee 1F]

Adding on to that, we have been using Bronsted more due to conjugate acid and base pairs which don't exist by the Lewis definition.
