= H+ + HPO;- Ka = 6.2 x 10-8 = H+ + SO?- Ka = 1.3 x 10-2 From the systems above, identify the conjugate pari that is best for preparing a buffer with a pH. of7.2. Explain your choice. Explain briefly how you would prepare the buffer solution described in (a) with the conjugate pair you have chosen. If the concentrations of both the acid and the conjugate base you have chosen were doubled, how would the pH be affected? Explain h pacity of the buffer is affected by this change in concentrations of acid and base.
