Autoprotolysis is basically a proton transfer between the same type of molecule. An example of a reaction that is autoprotolysis is 2H20 (l) ---> H30+ (aq) + OH- (aq). There is also suppose to be a reverse reaction arrow but I didn't know how to type it out haha. Hoped this helped!

Autoprotolysis is the proton transfer between the same type of molecule. In the case of water it favors being 2H2O rather than being H3O+ and OH-. This leads to autoprotolysis for water at 25 C being 1*10^-14 with H3O and OH being equal

If you break down the word into parts, you can deduce the meaning, too! Auto would indicate that autoprotolysis happens itself, hinting that it involves the same molecule. Proto can tell you that it involves protons.
