pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution:
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 10-14where 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...
