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. WebThis online pH calculator is designed to determine the pH of an aqueous solution of a given chemical compound.
