Review Constants | Periodic Table The temperature for each solution is carried out at approximately 297 K where K. = 1.00 x 10-16
Part A
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 K, 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
0.45 g of hydrogen chloride (HCl) is dissolved in water to make 7.0 L of solution. What is the pH of the
resulting hydrochloric acid solution?
Express the pH numerically to two decimal places.
