WebAnswer: pH = 3.39 As we have found the pH we can now use the following formula to find the pOH: 3.39 + pOH = 14 After subtracting 3.39 from both the pH and 14 we will get the pOH. Answer: (3.39 – 3.39)+ (14 – 3.39)= pOH 10.61 As we have found the pOH, we will now go ahead with finding the base concentration [OH – ]. WebIt says that the pH is equal to to the negative logarithmic value of the Hydrogen ion (H+) concentration, or pH = -log [H+] pH can alternatively be defined mathematically as the negative logarithmic value of the Hydroxonium ion (H3O+) concentration. Using the Bronsted-Lowry approach pH = -log [H3O+] pH values are calculated in powers of 10. great morning inspirational quotes
