Water does contain some hydronium (H3O) ions and hydroxide (OH) ions. These two are formed by the self-ionization of two water molecules but this happens rarely at pH=7. The process is in equilibrium when intact water molecules dominate the mixture. At equilibrium the molarities for the hydronium ion and hydroxide ion are equal.</p><p><br /></p><p>The process is reversible and the equation is:</p><p><br /></p><p>H2O + H2O <---> H3O(1+) + OH(1-)[/QUOTE]</p><p><br /></p>
