An amphiprotic substance is one which can both donate hydrogen ions (protons) and also accept them like water. Amphoteric means that they have reactions as both acids and bases.

An amphiprotic substance is a amphoteric substance that transfers H+ ions.

An analogy that helped me was that of a rectangle and a square.... a square is always a rectangle but a rectangle isn't always a square. The same goes for these terms as amphiprotic is always amphoteric but amphoteric molecules are not always amphiprotic

If an atom is said to be amphiprotic then that means that the atom has the ability to donate or accept protons whereas amphoteric is the ability of an atom to act as an acid or base.

I'm confused about the difference here between amphiprotic and amphoteric. Bronsted acids are substances that can donate hydrogen ions and vice versa for bases right? Or is this definition with conjugate or lewis acids and bases? Or does it have to do more with the characteristics of the substance and not how it reacts?

So does the amphiprotic substance mean it can be a Bronsted acid and base? While the Amphoteric substance relates to Lewis acids and bases?

As was stated previously, amphoteric describes a molecules ability to react with an acid or a base while amphiprotic is a molecules ability to accept or donate hydrogen ions. Additionally, amphiprotic molecules can also be amphoteric but amphoteric molecules are not always amphiprotic. For example, the diagnoal atoms near the metalloids band are amphoteric as they have the ability to react with acids or bases, however, they are not amphiprotic as they have no hydrogens to give off. However, water is both amphiprotic and amphoteric as it can react with acids and bases as well as serve as an acid or a base and give off or accept H in a reaction.

Are there any other compounds that can be both amphiprotic and amphoteric besides water?
