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_w of water. K_w = [H^+][OH^-] = 1.00 times 10^-14 where 1.00 times 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 The temperature for each solution is carried out at approximately 297 K where K_w = 1.00 times 10^-14. 0.30 g of hydrogen chloride (HCl) is dissolved in water to make 6.5 L of solution. What is the pH of the resulting hydrochloric acid solution? Express the pH numerically to two decimal places. pH = ____
