pH of a solution is defined as the negative logarthim of hydronium concentration.
pH = -log(H3O+)
The dissociation of HCl in water can be written as
HCl + H2O --------> H3O+ + OH-
Since HCl is a strong acid, the concentration of hydronium ion isequals to the concentration of the acid.
pH= -log(3.00*10^-3) = 2.523

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-] +...
