HC2H3O2 + NaOH --> NaC2H3O2 + H2O?

a. when the titration is only half over, what species are present in the reaction flask
b. what can be said about the pH at this point when the titration is half over?
c. what is the pH at the equivalence point of this titration? 7, >7, <7

  1. a. When half over, you have some HC2H3O2 not yet titrated, you have some extra water produced, some NaC2H3O2 (the sodium acetate salt) produced (present as Na^+ and C2H3O2^-).
    b. When half over, the pH = pKa
    c. The pH at the equivalence point is determined by the salt present; i.e., one has only water and the salt at that point. The pH of NaC2H3O2 (the salt of a strong base and a weak acid) is basic so the pH is >7 (about 8.5 or so).
