Calculate the pH change in a phosphate buffer when acid or base is added
a. If 50 ml of 0.01 M HCI is added to 100 ml of 0.05 M phosphate buffer at pH 7.2, what is the resultant pH? What are the concentrations of H2 PO 4- and HPO 4 2- in the final solution?
b. If 50 ml of 0.01 M NaOH is added to 100 ml of 0.05 M phosphate buffer at pH 7.2, what is the resultant pH? What are the concentrations of H2 P0 4- and HPO 4 2- in this final solution?
