WebJun 5, 2024 · pOH = − log([OH −]eq) = − log([B]initial) To find the pH, we then subtract the pOH from 14. Example 2 What is the pH of a 0.175 M aqueous solution of NaNH 2 ? Solution NH 2- is a strong base ( Kb > 1 ), so [OH −]eq = [NH − 2]initial. Thus, pOH = -log (0.175) = 0.757, and pH = 14.000 - 0.757 = 13.243 Exercise 2 WebSo the negative log of 5.6 times 10 to the negative 10. Is going to give us a pKa value of 9.25 when we round. So pKa is equal to 9.25. So we're gonna plug that into our Henderson-Hasselbalch equation right here. So the pH of our buffer solution is equal to 9.25 plus the log of the concentration of A minus, our base.
