After 2 mL NaOH has been added:
pH = 3.15, [H3O+] = 10-3.15 = 7.08*10-4 M, [OH-] = 10-14/10-3.15 = 1.41*10-11 M, pOH = 14-pH = 10.85
After 26 mL (1 mL before equivalence point) NaOH has been added:
pH = 6.1, [H3O+] = 10-6.1 = 7.94*10-7 M, [OH-] = 10-14/10-6.1 = 1.26*10-8 M, pOH = 14-pH = 7.9
After 27 mL (equivalence point) NaOH has been added:
pH = 8.88, [H3O+] = 10-8.88 = 1.32*10-9 M, [OH-] = 10-14/10-8.88 = 7.586*10-6 M, pOH = 14-pH = 5.2
