I have been asked to prepare a buffer solution at pH = 9.00,using one of the following weak acids and its conjugate base:
HA (Ka=2.7x10^-3)
HB (Ka=4.4x10^-6)
HC(Ka=2.6x10^-9)
a) Which acid should I use?
b) If 500 mL of 1.0M HC is mixed with 250mL of 0.50 NaC, what isthe pH of this buffer?
show all step and calcs
