Conjugate/Bronsted/Lewis

What is the difference between describing something as a conjugate base, a bronsted base, or a Lewis base?

Re: Conjugate/Bronsted/Lewis

The lewis definition of a base is the species that donates an electron pair.
The bronsted definition is the species that accepts a proton.
A conjugate base is, in a reaction, the species formed by the reactant acid after it donates a proton. So to clarify, a conjugate base is defined very similarly to a bronsted base but is really only referred to as part of a conjugate acid-base pair.

Re: Conjugate/Bronsted/Lewis

Lewis and Bronsted definitions have been explained above already, but just know that a conjugate base occurs when an acid donates an H+ and thus the product is now able to accept an H+ back in the reverse reaction.
