Distinguishing between the different definitions of acids and bases

Postby JamieVu_2C » Sun Dec 01, 2019 4:44 pm

What are the differences between the Bronsted, Lewis, and Arrhenius definitions of acids and bases? How does each definition make identifying acids and bases different?

A bronsted base is a proton accepter while a bronsted acid is a proton donor, lewis acids and bases are the same they are just described differently where a lewis acid accepts electrons and a lewis base donates electrons.
Arrhenius refers to acids and bases by OH- and H+ concentration so an acid puts more H+ into a solution while a base creates more OH- in a solution.

These do not make acids and bases different, they are just referred to differently.

Arrhenius acid: a compound that supplies H+ in water
Arrhenius base: a compound that supplies OH- in water

Brønsted acid: a compound that donates protons
Brønsted base: a compound that accepts protons

Lewis acid: an electron pair acceptor (i.e. H+)
Lewis base: an electron pair donor
