A student added 501 mL of 0.35 M NaOH to a buffer solution made up of 0.500 mol of citrate (A-), 0.500 mol of citric acid to 1.5 L of water (total volume = 1.5 L) (Ka = 7.41 x 10-4). A.) Calculate the pH of the initial buffer solution (before the addition of the acid).B.) Calculate the pH of the solution after the addition of HCl referenced above.C.) Did the buffer solution exceed its buffer capacity?(note: All pH calculations should be expressed with 3 sig. figs.)
