Answer:
Because of its amphoteric nature (i.e., acts as both an acid or a base), water does not always remain as H2O molecules. In fact, two water molecules react to form hydronium and hydroxide ions:
2H2O(l)⇌H3O+(aq)+OH−(aq)(1)
This is also called the self-ionization of water. The concentration of H3O+ and OH− are equal in pure water because of the 1:1 stoichiometric ratio of Equation 1 . The molarity of H3O+ and OH- in water are also both 1.0×10−7M at 25° C. Therefore, a constant of water ( Kw ) is created to show the equilibrium condition for the self-ionization of water. The product of the molarity of hydronium and hydroxide ion is always 1.0×10−14 (at room temperature).
Kw=[H3O+][OH−]=1.0×10−14(2)
Equation 2 also applies to all aqueous solutions. However, Kw does change at different temperatures, which affects the pH range discussed below.
H+ and H3O+ is often used interchangeably to represent the hydrated proton, commonly call the hydronium ion.
Equation 1 can also be written as
