Identifying the difference

[Jennifer Torres 2L]

How can you tell the difference between bronstead acids and bases and normal acids and bases? which problems do you use each one for?

[Faith Fredlund 1H]

On page 448 of the 7th edition of the textbook it states, "in the Lewis theory, the proton is the acid; in the Bronsted theory, the species that supplies the proton is the acid. In both the Lewis and the Bronsted theories, the species that accepts the proton is a base; in the Arrhenius theory, the compound that supplies the proton acceptor is the base."

Depending on the way the formula of the reaction is constructed, you should be able to determine acids and bases within the context of these guidelines for each of the theories.

[Rachel Dang 1H]

The difference is in the definition of what each type considers an acid or base.

Bronsted Acids and bases are more commonly used and considered a more widely accepted definition. Just be careful with what the problem asks so you know which definition to use.

[Madeera_Mian_3B]

Bronsted Acids is a proton donor, while Bronsted Bases is a proton acceptor. On the other hand, Lewis bases is a electron donor while Lewis acids accept electrons.

[Emilee Hosking 1D]

They way that I think of it is that with the Lewis acids and bases you are considering the transferring of electrons, while with Bronsted protons are being tranferred. Bronsted acids want to remove their H+, which removes a proton, whereas a Lewis acid accepts electrons from a lewis base.

[Javier_Ochoa_DIS_3J]

There are two definition you can use for acid and bases.
The Bronsted definition deals with the transfer of protons and the Lewis definition deals with the transfer of electrons.
