Calculate the volumes of 0.200 M hydrocyanic acid, HCN (Ka = 4.9 x 10–10) solution, and 0.200 M of sodium cyanide, NaCN, solution needed to prepare 100.0 mL buffer solution with pH = 9.5
Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.170 in KCN. For HCN, Ka= 4.9 x 10^-10 (pKa = 9.31). Use both the equilibrium approach and the Henderson-Hasselbalch approach.
