- Because water is an amphoteric substance, meaning it can be both acidic and basic; thus it is able to autoionize.
- What is autoionization?
A substance, in this case water, reacting with itself to create ions.
- What is Kw?
Kw is the equilibrium constant for the autoionization of water.
- Given that the Kw of pure water at 40oC is 2.29 x 10-14.
Calculate the [H+].
1.51 x 10-7 M
