Problem- Part a) If an acetic acid/sodium acetate buffer solution is prepared from 100ml of 0.10M acetic acid, what volume of 0.10M sodium acetate must be added to have a pH of 4.00
Part b) When mixed in appropriate amounts, which of the following mixtures can produce an effective buffer solution- 0.20M HCN and 0.10M KCN , or 0.20M HCL and 0.10M KOH, or 0.20M CH3CO2H and 0.10 M HCO2H, or 0.10 HCL and 0.010 KCL , or none of the above
Part c) What mass of solid NaCH3CO2 should be added to 1.0L of 0.5M CH3CO2H to make buffer with a pH of 7.21. pKa of CH3CO2H=7.21
