You can obtain the pH of a 0.100 M HCl solution by assuming that all of the H3O+ ion comes from the HCl, in which case the pH equals –log 0.100 = 1.000. But if you want the pH of a solution that is 5.00 x 10-8 M HCI, you also need to account for H3 O+ ion coming from water. Note that the auto-ionization of water is the only equilibrium you need to account for. What is the pH of 5.00 x 10 3 м HC1? pH =
