Homework Statement
i was wondering if anyone knows why water is ignored in the autoionization of water? thanks
Homework Equations
H2O+H2O= H3O+OH
Kc=[H][OH]
Autoionization of water is the process in which water molecules spontaneously dissociate into hydrogen ions (H+) and hydroxide ions (OH-).
The movement of water molecules and their interactions with each other cause some molecules to gain or lose a proton, resulting in the formation of H+ and OH- ions.
The autoionization of water is essential for many chemical reactions, as it provides a source of H+ and OH- ions, which are involved in acid-base reactions and many other chemical processes.
The autoionization constant (Kw) of water is a measure of the equilibrium between H+ and OH- ions in water. It has a value of 1.0 x 10^-14 at 25°C.
As temperature increases, the autoionization of water also increases. This is because higher temperatures provide more energy for the movement and interaction of water molecules, leading to a higher likelihood of ion formation.
