Explain using your results. 3)Which solution undergoes the smallest change in pH (most effective buffer)? Which solution undergoes the largest change in pH (least effective buffer)? 4)Why can’t you make a buffer out of a strong acid (HCl) and a strong base (NaOH)?
Post-Lab Questions 1)For solution 7, calculate the pH after the addition of 1.0 and 20.0 mmol of HCl and NaOH, respectively. Compare your calculated values to your “experimental” ones.
