Webyou can enter the concentration of HNO 3 acid in mol dm -3 and check the pH value. Enter concentration of nitric acid in mol dm-3. Calculate pH. Answer. Note: This online calculation is not suitable for very dilute solutions of HNO 3 (such as 0.0000005 mol dm -3) because, those solutions give very low H + ion concentration. In those cases, pH ...

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.

WebOct 27, 2024 · pKw = pH + pOH At 25 °C, the value of Kw is 1.0 × 10 − 14, and so: 14.00 = pH + pOH The hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 − 7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH = − log[H3O +] = − log(1.0 × 10 − 7) = 7.00 pOH = − log[OH −] = − log(1.0 × 10 − 7) = 7.00
