So, given a pH value of 5.5 you can find the hydrogen ion concentration: Diving by negative one and taking the inverse … Web1. pH values do not reflect directly the relative strength of acid or bases. A solution of pH = 1 has a hydrogen ion concentration 100 times that of a solution of pH = 3 (not three times). A 4 x 10-5 N HCI is twice concentrated as a 2 x 10-5 N HCI solution, but the pH values of these solutions are 4.40 and 4.70 (not double).
