Webthan the pH value, both exist predominately in the protonated form at pH = 1.81. N N NH 3 COOH H H N N NH 3 COO H H acid conjugatebase (b) As pH = 6.05 is higher than its pK a value, the α-COOH group will exist predominately in its conjugate base form. The pK a value for the α-NH 3 + group is higher than the pH value so it will exist ... WebSo I can plug in the pOH into here, and then subtract that from 14. So the pH is equal to 14 - 4.92 and that comes out to 9.08 So the pH = 9.08 So we're dealing with a basic solution …
