Auto-ionization is when one water molecule acts as an acid and another acts as a base.


Concept #1: Through auto-ionization the ionization constant of water can be determined.

Concept #2: Like other equilibrium constants, Kw is also affected by changes in temperature.

Example #1: A particular aqueous solution at 50ºC contains 3.7 x 10-4 M of hydronium ions. Calculate the [OH-] and identify solution as acidic, basic, or neutral.

Practice: Chemistry student prepared an aqueous solution at 30ºC. If the solutions contains 7.42 × 10−9 M of hydroxide ions, calculate the pH.

Practice: Calculate the Kw of pure water given the pH = 6.34.
