Acid and Bases definition
Can someone please explain the differences between the definition between Lewis, Bronstead, and Arrhenius definitions of acids and basese becuase they are quite similar and I have trouble differentiating between the two.

Re: Acid and Bases definition
Arrhenius refers to a solution in water, so Arrhenius acids are those that raise the number of [H+] in a solution while an Arrhenius base raises the concentration of [OH-]. Lewis acids are electron acceptors while Lewis bases are electron donors; and finally, Bronsted Acids are proton donors, whereas Bronsted Bases are proton acceptors. Hope this helps!

Re: Acid and Bases definition
Bronstead Acids can donate a proton (H+)
Bronstead bases accept a proton (H+)
Lewis Acids accept a lone pair
Lewis Bases donate donate a lone pair
the bronstead acid/base definition is very similar to arrhenius acid base definitions
Bronstead bases accept a proton (H+)
Lewis Acids accept a lone pair
Lewis Bases donate donate a lone pair
the bronstead acid/base definition is very similar to arrhenius acid base definitions

Re: Acid and Bases definition
Bronsted acid is a proton donor and Lewis acid is an electron acceptor. They are both acids and very similar but different ways to define them.
Re: Acid and Bases definition
The Lewis definition pertains to the electrons pairs while the Bronsted definition pertains to the proton. A lewis acid accepts an electron pair while a lewis base donates an electron pair. A Bronsted acid donates a proton (H+) while a Bronsted base accepts a proton (H+). The lewis definition is more broad than the bronsted definition.

Re: Acid and Bases definition
A good way I remember that Bronsted refers to protons and Lewis refers to electrons is to remember that Lewis structures show the electron arrangement. :)

4. Brownsted Lowry Acids are H+ donors
Properties of Bases:
1. taste bitter

Re: Acid and Bases definition
Hello! Bronstead-Lowry bases accept an H+(proton) and Bronstead-Lowry acids donate the H+ (proton). Lewis bases donate a lone pair of electrons, while lewis acids accept a lone pair of electrons.
