n analytical chemist is titrating
108.4mL
of a
0.4400M
solution of nitrous acid
HNO2
with a
1.000M
solution of
NaOH
. The
pKa
of nitrous acid is
3.35
.Calculate the pH of the acid solution after the chemist has
added
54.08mL
of the
NaOH
solution to it.
Note for advanced students: you may assume the
final volume equals the initial volume of the solution plus the
volume of
NaOH
solution added.
