In the titration of acetic acid (CH3COOH) and sodium hydroxide (NaOH), what are the major sepcies present at the following points?
a) Before any NaOH is added (at the start of the titration).
b) In the buffer region. Are there any spectator ions?
c) At equivalence point. What is equivalent at this point? What has been used up? Are there any spectator ions?
d) Beyond equivalence point. What has been added since the equivalence point? Has anything reacted further since the equivalence point?
