Calculate the pH of a 5.2 x 10-8 M HCl solution. Report your answer to the hundredths place. < Feedback pH = 6.61 Because the concentration of the HCl solution is so small, you must account fot the autoionization of water when calculating the pH. What fraction of the total H+ in this solution is from the HCI? Report your answer to the hundredths p Start with the charge balance equation for this solution. fraction: 0.21 [H+] = [OH-] +...
