Difference between Arrhenius, Bronsted, and Lewis Acids/Bases

Postby AGaeta_2C » Sun Dec 01, 2019 6:22 pm

My TA differentiated between these types of acids and bases during discussion and I figured it might help someone if I posted it here.

Arrhenius
Acid: gives off H+
Base: gives off OH-

B-L
Acid: proton donor
Base: proton acceptor

Lewis
Acid: electron pair (usually nonbonding 2e-) acceptor
Base: electron pair (2e-) donor

Arrhenius is a little more specified towards aqueous solutions, which is why the bronsted definition is used more generally.

This is pretty helpful, thanks for sharing! Does anyone happen to know which definition is used most commonly, and why?
