What exactly is autoprotolysis? Also, can someone please explain what the autoprotolysis constant represents.

Autoprotolysis is when a proton (H+) is transferred from 1 molecule to another molecule that is identical to the first. For example: 2 H2O --> H3O+ +OH- in that reaction, a proton is transferred from 1 water to another, making 1 a bronsted base and the other a bronsted acid.

The autoprotolysis constant represents the equilibrium constant for the equation above. So the fact that the constant is pretty small (10-14ish) means that in a body of water, most of the molecules exist as H2O.
