Amphiprotic [ENDORSED]

[Kathleen Vidanes 1E]

Are there any other molecules that are amphiprotic besides water? If so, what are they?

[Chem_Mod]

Several, any of the polyprotic acids or bases that have released or taken up one proton and could take up another proton or release the proton they have.
E.g., HSO₄^- which can become H₂SO₄ or SO₄^2-

If I have time in class this week I will discuss examples.

[CameronJohari1J]

An additional amphiprotic substance is hydrogen carbonate ion HCO3-
It can either donate its hydrogen to become CO3 (2-) or accept another hydrogen to become H2CO3

[Sabah Islam 1G]

There are other molecules that are amphiprotic besides water, which include the hydrogen carbonate ion, hydrogen sulfate ion, and the dihydrogen phosphate ion.

[Michael Cheng 1C]

What is the difference between amphiprotic and amphoteric

[Cooper1C]

Amphiprotic is the ability of a molecule to both accept and donate protons.

Amphoteric is the ability of a molecule to react with both acids and bases.
