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?

Re: Brønsted acids and bases
Hi! A Bronsted acid is a proton (H+ ion) donor, while a Bronsted base is a proton acceptor.

Re: Brønsted acids and bases
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.
Re: Brønsted acids and bases
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.

Re: Brønsted acids and bases
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 !

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.

Re: Brønsted acids and bases
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.

Re: Brønsted acids and bases
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.
