Question

How much NaOH (in moles) must be added to 1 L of a buffer solution that is 1.8 M in acetic acid and 1.2 M in sodium acetate to result in a buffer solution of ph 5.22? Assume volume to remain constant.

Answer 1

The initial molar concentration of acetic acid in the buffer solution:
C
A
=
1.8

M
The initial molar concentration of sodium acetate in the buffer solution:
C
S
=
1.2

M
The volume of the buffer solution:
V
=
1

L
The final pH of the resulting solution:
x
=
5.22
