Autoprolysis

Postby Marni Kahn 1A » Tue Jan 14, 2020 9:59 am

Are there any other examples besides H20 that demonstrates autoprolysis (one molecule transfers a proton to another molecule of the same kind) and are significant?

There are other examples of molecules beside water than can do autoprotolysis due to them being amphiprotic. Examples include ammonia, acetic acid, and H2SO4. These aren't really significant; the autoprotolysis of water is the important one you have to know for acid/base equilibria.

The only other significant autoprolysis examples I could think of are 2NH3 (ammonia) forming NH2- and NH4+ as well as 2CH3COOH (acetic acid) forming CH3COO- and CH3COOH2+. In both examples, a hydrogen atom is removed from one molecule and given to the other same molecule. In the examples however, ammonia would be a basic solution and acetic acid would be an acidic solution.

Adding to this conversation, what does amphiprotic mean again?

Amphiprotic means that a species can accept or donate a proton / H+.

It's also important to remember that amphiprotic is different than amphoteric, which means that it reacts with both acids and bases.

Amphiprotic is specific to the donation and accepting of protons specifically.

So just to clarify something being amphiprotic means its specific to the donation and accepting of protons, while autoprolysis means a hydrogen atom is removed from one molecule and given to the other same molecule?

Does autoprotolysis have to do with the donation acceptance of a hydrogen ion but amphiprotic means donation and accepting of protons, and so do acids and bases take place in amphiprotic processes?
