20 mL of 025 M of NH_3 is titrated with 0.40 M HCl. Calculate the pH of the solution after 20 mL HCl is added. K_b NH_3 = 1.8 times 10^-5 7.00 1.12 12.50 4.74 Beyond the equivalent point, [H_3O^+] from NH_4^+ dissociation is negligible and the pH should be calculated from the excess strong acid. See Section 16.8.
