Chapter 8, Acid-base equilibria
This equation is called the autoionization of water and its equilibrium constant is known as the water autoionization constant Kw. At 25°C it is equal to Kw =@H3O+D@OH-D=1.0μ10-14 Now, we have seen that the equilibrium constant of a sum of two reactions is the product of the equilibrium constants of the summed reactions.
