Calculate the pH of a 0.63 M solution of a weak acid, AH, for instance CH3COOH, and 1.46 M of a salt derived by its conjugate base, ANa, like CH3COONa. The acid dissociation constant, Ka , is 1.89e-4. What is the pH if 31 mL of 0.165 M of a strong acid, like HCl, is added to 100 mL of the buffer solution? What if a strong base, like NaOH, is added with the same ammount instead ? pH ← please insert your values Add acid = _______ Add base = ________
