In this problem, we are asked to determine much more acetic acid (pKa = 4.76) than acetate should be in solution to maintain a pH of 4.00.
A solution that contains a weak acid (acetic acid) and its conjugate base (acetate) is a buffer solution. The pH of a buffer solution can be determined using the Henderson-Hasselbalch equation.
How much more acetic acid (pKa = 4.76) than acetate should be in solution to maintain a pH of 4.00?
a) 2.13 times more
b) 5.75 times more
c) 0.47 times more
d) 0.00 times more
e) 0.17 times more
