Brønsted acids and bases

[Emma Swanton 1G]

Achieve Q2: Which of these substances is amphoteric, that is, it can act as a Brønsted acid and a Brønsted base?
Can anyone explain what Brønsted acids and bases are?

[Gianna Greco 1G]

Hi! A Bronsted acid is a proton (H+ ion) donor, while a Bronsted base is a proton acceptor.

In addition to the response above, an amphoteric substance would have those qualities of an acid and a base. To determine this we can look for at least one H atom in the compound because it means the compound can loose that H atom making it an acid. To determine if it has basic aspects we can look for a compound that can accept a proton, so something with a negative charge could work.

Bronsted Acids are H+ (proton) donors. They produce H3O+ when it combines with water and typically start with H or ends in -COOH. Bronsted Bases are H+ (proton) acceptors. They produce OH- when it combines with water and typically have a metal cation and end in -OH or has N in it.

Hello,

Bronsted acids are proton donors while bronsted bases are proton acceptors. So an amphoteric compound can be either a base or an acid determined on the reaction

Hope this helps !

A Bronsted acid is a proton donor, whereas a Bronsted base is a proton acceptor.

Hi,
As others mentioned above, a Bronsted acid is a substance that can donate a proton (H+) known as a proton donor, and a Bronsted base is a substance that can accept a proton (H+), known as a proton acceptor.

Bronsted acids and bases are one way of defining what acids and bases are (others include Lewis acids and bases, and Arrhenius acids and bases). In this definition, a Bronsted acid is a proton donator, and a Bronsted base is the proton acceptor.

A Bronsted acid is a proton donator and a Bronsted base is a proton acceptor

[Emma Goellner 2I]

Bronsted acids donate protons, while Bronsted bases accept protons. An example of an amphoteric compound is water, since it has the potential to act both as an acid or a base depending on the circumstances.
