WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH. To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH. WebBecause [H+] × [OH-] = constant, OH - concentration can be calculated using H + concentration and constant. This constant value depends on temperature and for 25 0, it is 1.0 * 10 -14 mol 2 dm -6 . Let's take H + concentration of an aqueous solution as 0.1 mol dm -3 at 25 0 C. [H +] × [OH -] = 1.0 * 10 -14 0.1 × [OH -] = 1.0 * 10 -14
