Autoprotolysis vs Autoionization

Postby Altamash Mahsud 1I » Mon Jan 13, 2020 7:12 pm

When first learning about the concept that water molecules interact with each other and a small percentage of them form H3O+ and OH-, I was taught that it was called the autoionization of water. In lecture, it said the autoprotolysis of water, what is the difference between the two terms in this case?

An explanation that I found online said that "the key difference between autoionization and autoprotolysis is that autoionization is the conversion of a neutral state of a chemical species into an ionized state whereas autoprotolysis is the transfer of a proton between two identical chemical species to form ionized forms."

When it comes to water, I believe the two terms can be used interchangeably. Kw is referred to as either the autoprotolysis constant of water or the autoionization constant of water. They basically mean the same thing.
