Webb26 mars 2024 · Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl –, would also have a concentration of 0.100 M.) The pH is thus –log (0.100) = 1.000.
