Aspirin (C9H8O4) is a weak monoprotic acid with a Ka of 3.27 x 10^-4. Suppose you dissolved 0.650g of aspirin (the amount of two tablets) in 200.0mL of water ( a reasonable glass of water) and titrated it with 0.100M NaOH. Give the following:

a) Initial pH
b) Volume to reach equivalence point
c) pH at equivalence point
d) Volume to reach half-equivalence point
e) pH at half-equivalence point
f) Volume to achieve a pH of 9
