In your report be sure to compare and contrast the system you used in your investigation with the carbonic acid/carbonate buffer system in the blood.
a) how are the system similar
b)how are they different
The slope of the Gran Plot for the titration of KHP with NaOH was found to be -1E-05. Use this to determine ka2. Other values that may be of importance: concentration was measured

calculate the pH of the buffer after the addition of 0.15 mL of 6M HCl based on the known value of Ka for acetic acid
there is a no change in VMAX and an increase in KM,app. E. As [I] increases, there is a decrease in VMAX and no change in KM,app.
Kp for the reaction of SO2(g) with O2 to produce SO3(g) is 3 × 1024 . Calculate Kc for this equilibrium at 25ºC. (The relevant reaction is 2SO2(g) + O2(g) 2SO3(g).)
