WebJan 8, 2024 · To find pH, we take the -log ( [H+]). pH = -log (1) = -0 = 0. Therefore a 1M solution of HCl has a pH of 0. The same idea applies to strong bases. Suppose we had 1M NaOH. NaOH --> Na+ + OH-, so pOH = -log ( [OH-]) = -log (1) = 0. To find pH, we then plug our value into pH + pOH = 14, which tells us that the pH of a 1M solution of NaOH is 14. the pearl suites istanbulWebFigure 6.5.1: pH paper indicates that a 0.l-M solution of HCl (beaker on left) has a pH of 1.
