<Week 3 Assignment: Acid-Base Equilibria
+ pH of a Strong Acid and a Strong Base
pH is a logarithmic scale used to indicate the hydrogen ion
concentration, [H+], of a solution:
pH = -log[H+]
Due to the autoionization of water, in any aqueous solution, the
hydrogen ion concentration and the hydroxide ion concentration,
[OH-], are related to each other by the Kw of water.
Kw = [H+][OH-] = 1.00 x 10-¹4
where 1.00 x 10-14 is the value at approximately 297 K. Based on
this relation, the pH and pOH are also related to each other as
14.00 = pH + pOH
