WebMar 26, 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 … WebDec 12, 2024 · This tells us that we get equal numbers of H+ and Cl- atoms, and that number is the same as the number of HCL molecules. So if we start with 6.2 x 10-11M HCl, we'll have 6.2 x 10-11M moles each of the two ions. Therefore [H +] = 6.2 x 10 -11 M. The log of 6.2 x 10 -11 M is -10.2. The negative log is therefore 10.2, and that is the pH.
