amphiprotic vs. amphoteric

Postby Stephanie tran 1J » Sun Dec 10, 2017 3:57 pm

according to the textbook definition, amphiprotic specifically pertains to water molecules, but I noticed In the homework problems that amphiprotic referred to other compounds as well acting as both proton donors and acceptors; What's the main difference between amphiprotic and amphoteric and is amphiprotic more prevalent to acids and bases?

They are similar but amphiprotic is more specific. Amphiprotic is when something can donate or receive a proton. Amphoteric is when something can act as an acid or a base.

An example of what Stephanie said would be water. Water is amphoteric because:
Water as a base:
Water as an acid:
In the above reactions, H+ is being donated/accepted. Hence, water is not only amphoteric, but also amphiprotic.
Other examples of amphiprotic compounds are would be and amino acids with carboxyl groups (--COOH) groups.

On the other hand, while Al2O3 reacts with both acids and bases, it cannot by definition be amphiprotic since it doesn't have H.
