WebBecause pH = 13, this solution is a strong basic solution. We can substitute pH = 1 in pH equation. pH = -log [H +] 13 = -log [H +] [H +] = 1 * 10 -13 mol dm -3 Because pH + pOH = 14 at 25 0 C. pH + pOH = 14 13 + pOH = 14 pOH = 13 From pOH equation, OH - … Therefore, concentration of HCl is 11.8 mol dm-3. pH = -log 10 [11.8] pH = -1.07; … Therefore, for 0.0025 mol of KOH, 0.0025 mol HNO 3 is required. But, in this case, … pH calculator of aqueous weak acid solution. K a values of weak acids are … As an example, at 25 0 C, pH + pOH = 14 . This constant can be calculated from the … H + concentration varies from 0.1 mol dm-3 to very low values. At very low H + … You can see the pH value is 12. If pH value is 12, OH-concentration should be 0.01 … Calculate pH of HNO 3 using the pH equation.
