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. Web1.0 x 10^-11. The pH of an aqueous solution is 0.8. What is the hydrogen ion concentration? 0.16. What is the pH of a 1.0 M solution of HCl. 0. The pH scale is a range from: 0-14.

WebFigure 6.5.1: pH paper indicates that a 0.l-M solution of HCl (beaker on left) has a pH of 1. The acid is fully ionized and [H 3O +] = 0.1 M. A 0.1-M solution of CH3CO2H (beaker on right) has a pH of 3 ( [H 3O +] = 0.001 M) because the weak acid CH3CO2H is only partially ionized. WebpH = - log [H 3 O +] Similarly, pOH is the negative of the logarithm of the OH - ion concentration. pOH = - log [OH -] pH + pOH = 14 The equation above can be used to convert from pH to pOH, or vice versa, for any aqueous solution at 25C, regardless of how much acid or base has been added to the solution.
