Amphiprotic v. amphoteric

Postby ayushibanerjee06 » Sat Dec 07, 2019 2:36 pm

On the final, how would you show that a molecule is either amphiprotic or amphoteric through using reactions?

Also, what would be an example of a molecule that would be amphoteric but not amphiprotic?

Amphiprotic means it can donate or accept a proton, and amphoteric means it can act as a base or acid. All amphiprotic molecules are amphoteric, but not the other way around. An example of a amphoteric
molecule that is not amphiprotic would be Al2O3. It does not contain any H's, but it can act as both an acid and a base.

An amphiprotic molecule will done a proton or accept a proton, thus acting as a Bronsted acid or base. An amphoteric molecule will act as Bronsted base/acid and a Lewis acid/base.

Thus, an amphiprotic molecule will be an amphoteric molecule, but an amphoteric molecule may not be an amphiprotic molecule.
