Amphiprotic

Postby Kathleen Vidanes 1E » Sun Dec 03, 2017 10:40 pm

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

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 SO42-

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

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

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

What is the difference between amphiprotic and amphoteric

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.

See page 469 in the textbook.
