Buffers in Medicine
The Henderson-Hasselbalch equation relates the pH of a buffer
solution to the pKa of its conjugate acid and the ratio of
the concentrations of the conjugate base and acid. The equation is
important in laboratory work that makes use of buffered solutions,
in industrial processes where pH needs to be controlled, and in
medicine, where understanding the Henderson-Hasselbalch equation is
critical for the control of blood pH.
Part A
As a technician in a large pharmaceutical research...
Use the Henderson-Hasselbach equation to calculate the pH of
each solution:
I figured out part A by myself because the numbers were already
in Molarity for me so I just plugged in numbers and calculated.
B. A solution that contains 0.785% C5H5N by mass and 0.985%
C5H5NHCl by mass. (Here, I don't know what to do with the %'s to
get the molarity in order to find the pH.)
C. A solution that contains 15.0 g of HF and 25.0...
