A different phosphate buffer is now put to test to see if it will maintain the pH of an enzyme solution if a strong base is added. This buffer solution was prepared to a final volume of 100.0 mL with concentrations of the salts of the conjugate acid/base pairs as following: 0.150 M Na2HPO4(aq) and 0.100 M KH PO (aq). What are the pH and the pH 2 4 change resulting from the addition of 80.0 mL of 0.0100 M NaOH(aq) to the buffer solution
