Need help with part C of this problem.
A 75.0-mL volume of 0.200 M NH_3 (K_b = 1.8 times 10^-5) is titrated with 0.500 M HNO_3. Calculate the pH after the addition of 27.0 mL of HNO_3. Express your answer numerically. Your answer is the pK_a. The pH of a buffer is equal to pK_a only when the equilibrium concentrations of acid and base are equal. A 52.0-mL volume of 0.35 M CH_3COOH (K_a = 1.8 x 10-5) is titrated times with 0.40 M NaOH. Calculate the pH after the addition of 21.0 mL of NaOH. Express your answer numerically. pH = 4 67
