[8] 12. Calculate the pH of the solution at each of the following points in the titration
of 15.0 mL of 0.250 M propanoic acid (C2H
5
COOH) with 0.100 M NaOH (aq):
a)
The initial pH
b)
The point of half-neutralization
c)
The equivalence point
d) When 2.0 mL of excess 0.100 M NaOH (aq) has been added (i.e. 2.0 mL past the
equivalence point).
