WebJul 9, 2014 · pH = -log [H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl -> H + + Cl− (notice the 1:1 ratio of HCl and H +) A 1M HCl solution has a pH of 0 WebpH = -log[H+] = log 1/[H+] The pH scale ranges from 0 to 14, with 7.0 being neutral. Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2.
