Autoprotolysis

Postby Jarrett Peyrefitte 2K » Tue Jan 14, 2020 5:55 pm

Can someone explain what autoprotolysis is? When does it occur? Why and How?

it's proton transfer between two of the same atom. one of them acts as a bronsted acid and the other as a bronsted base.

It occurs naturally and emphasizes the amphoteric nature of water (the ability to both give and accept a proton).

One important point to add: autoprotolysis can occur between molecules other than water.

The ability to accept and donate a proton is amphiprotic, while amphoteric is the ability to react with both acids and bases. :)

Water is amphiprotic and can thus act as both a proton donor and a proton acceptor. Therefore, when there are two water molecules, one of them loses a proton(H+) and the other accepts it, resulting in a H3O+ and a OH- molecule.

Autoprotolysis can be shown using H2O and is the proton transferring of two of the same atom

Autoprotolysis is the naturally occurring transfer of protons between the same type of molecule.

Oh my bad - thank you for the correction :)
