Amphiprotic vs amphoteric

Postby Hannah Lee 2F » Fri Dec 06, 2019 3:12 am

What's the difference between the two terms? Are they normally used interchangeably?

Amphiprotic (think proton) refers to a molecule that can donate or accept a proton. Of course, this means that it can act as both an acid and a base. Amphoteric means the same thing but the term is a little more general, whereas amphiprotic is referring to the specific idea of protonation/deprotonation.

For all intents and purposes, they mean the same thing.

Amphoteric means that a molecule can act as either an acid or a base. Amphiprotic describes a molecule that can donate or accept a proton. Water is a good example of an amphoteric molecule that is also amphiprotic. Also, although an amphiprotic molecule is always amphoteric, an amphoteric molecule is not always amphiprotic

An amphiprotic species refers to the characteristic of being able to act as both an acid and a base. Amphoteric refers to the same thing, but an amphiprotic substance is an amphoteric substance that transfers H+ ions.
