From the titration curve:
Equivalence point = 60 mL pH = 9
Half-equivalence point = 30 mL pH = 5
What is the most likely identity of the species undergoing titration?
a. hydrobromic acid (HBr); Ka = 1.08 x 109
b. acetic acid (CH3CO2H); Ka = 1.8 x 10-5
c. ammonia (NH3); Kb = 1.8 x 10-5
d. sodium acetate (NaC2H3O2); Kb = 5.6 x 10-10
