(a) What is the initial pH of the 0.20 M C6H5COOH(aq)?


(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 half stoichiometric 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.

Please show how to do it not just the answers.
