Posted by Val on Friday, March 12, 2010 at 3:58pm.

Suppose that 30.0 mL of 0.20 M C6H5COOH(aq) is titrated with 0.30 M KOH(aq). Refer to table 1 and table 2.
(a) What is the initial pH of the 0.20 M C6H5COOH(aq)?
Using ICE i found to be 2.46

The rest I do not know how to set up or solve...

(b) What is the pH after the addition of 15.0 mL of 0.30 M KOH(aq)?


(c) What volume of 0.30 M KOH(aq) is required to reach halfway to the stoichiometric point?
mL

(d) Calculate the pH at the halfway point.


(e) What volume of 0.30 M KOH(aq) is required to reach the stoichiometric point?
mL

(f) Calculate the pH at the stoichiometric point.
